Could be, but I'm not convinced.  Given that Howe doesn't say
anything about partners taking hands or otherwise touching each
other, the phrase "gentlemen passing to the outside of the ladies"
would suggest to me that if he indeed means for head couples
to switch places with the other head couple, then they'd do it
by having each head lady pass between the members of the opposite
head couple--that is, by dancing the action described in modern
terminology as "head couples pass through", but with dancers
facing towards their partners instead of in their direction of
travel.  While it is actually possible for all four couples to
cross the set in this fashion at the same time without collisions,
I doubt that such an action would have been common in the 19th
century.
I went to the American Ballroom Companion search page
     
https://memory.loc.gov/ammem/musdiquery.html
and did full text searches for such phrases as
     chasse across
     all chasse
     all chasse across
Below are some passages I found that I think support the idea that
"chasse across" means for dancers to exchange places with partners
rather than with opposite couples.  I freely admit that I found many
other passages where "chasse across" was used without explanation
or with an explanation that I didn't find entirely clear.  Possibly
I've allowed my favored hypothesis to bias my selection of passages
to quote, or to bias my interpretation of the passages I've quoted.
Of course anyone can repeat my searches and/or similar ones (e.g.,
for "chassa across", "chasse croise", etc.), examine the results,
and come to their own conclusion.  And again, I don't claim any
credentials as a dance historian.  [Deborah, if you consult some
more serious researcher(s) of historical dance, such as any of
those named in Michael Barraclough's recent message, I'd be
interested in knowing what they say.]
 From _Dancing And Its Relations to Education And Social
Life_ by 
Allen Dodworth (Harper & brothers, New York, 1900), page 93
[description of fifth quadrille figure, seventh movement]:
    ... All Chassé Across. All standing side to side with partners,
    the lady a little in advance, all slide sideways three times,
    lady to left in front, gentleman to right, thus passing or,
    crossing each other, then all balance once forward and once
    backward; repeat the three slides going back to places, lady
    again in front. All then turn to partners and make the
    concluding salutations. ... 8 bars.
 From _The Ball-Room Monitor, Or, Guide to the Learner_,
by Professor 
C. Brooks (third edition, J. H. Johnson, Philadelphia, 1866), p. 49:
    CHASSE ACROSS.--Gents move to right, ladies to left, 4 bars;
    ladies to right, Dechasse, gents to left, 4 bars; Turn corners,
    swing corners or allemande left. All the gents turn the ladies
    on their left with the right hand, partners with left, 8 bars.
Note that if dancers were to face partners and chasse across the set
to opposite couples' places (rather than facing into the set and
moving to partners' places), the gents would have to move to the
left and the ladies to the right.
 From _The Dance of Society_, by Wm. B. De Garmo (W. A.
Pond & Co., 
New York,1875), pp. 56-57:
     * Chassé Croisé.--To move across, or past partners, or other
       designated persons.
     * Déchassé.--To return.
     * Chassé Croisé et Déchassé (Chassé across and back--usually
       abbreviated by prompters to chassé across.)--To cross and
       recross partners, or other designated persons, 4 steps,
       2 meas. each way. (See No. 2 Quad., p. 25.)
     * All Chassé.--An abbreviation for All Chassé Croisé, Balancé
       et Dechassé, and performed by the entire set at the same time.
       It is executed as follows: Chassé across partners, 2 measures;
       balancé sur place (turning sufficiently to face partners),
       2 measures; déchassé, 2 measures; balancé sur place or rest,
       2 measures; in all, 8 measures--16 steps. In crossing and
       recrossing partners in All Chassé, the ladies always pass in
       front: the centre of the set is front.*  N. B.--The term "All 
       Chassé," does not always imply the entire figure above
       described, as may be seen in the last figure of the 2d No.
       Prince Impérial, p. 39. But the full figure is implied unless
       a break or change is made and some other figure substituted.
       This is further exemplified in No. 2 of the Caledonians: "All
       balance to corners" and exchange partners. If the exchange of
       partners were not understood in this Quadrille, "all balance
       to corners" would imply to balance to corners, to turn the
       person to whom you balance and return to partners. See also
       "Forward Two" in Gavotte, p. 30. This license is freely
       indulged in by prompters in New England to produce a "variety
       of changes." They seldom "call" the figures of the quadrille
       (1st set) in their original form.
A footnote on p. 25 of the same book reads:
     Chassé Croisé et Dichassé (usually abbreviated by prompters to
     Chassé across)--to cross and recross--to move across and back,
     i. e., the partners face each other; each then takes four steps
     forward and four backward, the partners passing and repassing
     each other, the ladies always passing in front--nearest the
     centre.
Note how De Garmo says that partners face each other and also that
they pass each other (not that they pass the opposite couple).
 From _The Quadrille and Cotillion Panorama_, by Thomas
Wilson 
(R. & E. Williamson, London, 1822), pp. 13-14:
     Change Places,
     Is when the Lady and Gentleman, partners to each other, move
     from their proper places, and take each other's situation;
     the Lady taking the situation of the Gentleman, and the
     Gentleman that of the Lady; or, when they take the place of
     any other person in the Quadrille. Though this Figure is
     called "Chassé across and back again" in French, yet in
     English it should be called "Change Places."
 From _Elements and Principles of the Art of Dancing_,
by J. H. 
G[ourdoux-Daux], translated by V. G. (J. F. Hurtel, Philadelphia
1817), pp. 65-67:
     TRAIT FOR PERFORMING CHASSÉ ACROSS.
     To perform this trait, the gentlemen of the opposite couples,
     passing behind their partners and going to the right, will
     do ...  In order to return to their first stands they will 
     repass behind their partners, doing ...
     In the performance of the figure of this trait, the ladies
     must go towards their left when the gentlemen are going to
     their right hand; and, consequently, they cannot begin with
     the same foot.  ...
     To perform the chassé across, the ladies will, going to the
     left and passing before their partners, do ... In order to
     return turn to their right, the ladies will ...
     The ladies and gentlemen will perform the chasse across
     together, the first beginning to move to the left and the
     last to the right. This trait is composed of eight bars. It
     is called chassé eight or chasse all, when it is done by
     all the dancers of the cottilion at once.
My ellipses replace long descriptions of footwork (far more
complex than a simple sliding side-step) in the original text.
 From _The Amateur's Vademecum: A Practical Treatise
on the Art 
of Dancing, by E. B. Reilley (J. Nichlas, Philadelphia, 1870),
p. 211:
     * Chasse. Execute the pas glissade crosswise.
     ...
     * Chasse de Cote, or Chasse Crosie, or Chasse de Chesse.
       Lady and gentleman cross each other sideways. 4 bars.
     ...
     * Chasse huit. All eight chasse across each partner.

https://books.google.com/books?id=XkJKAAAAYAAJ&printsec=frontcover&…
 
 
 A variety of words follow it: "chassa round to the left," "chassa
across," "chassa de chassa,"chassa croissez," "chassa out,"
etc. To me, that would indicate that, as now, "chassa" is simply the footwork of
a sliding step, with the direction of that step following. I did find at least one example
of "chassa across partner," which makes me think that a simple "chassa
across" would be across the set.
 
 I did find this description: "All Chassa: Each couple facing their own partner and
chassa across each other four steps the gentlemen passing to the outside of the ladies and
back the same finishing with a bow and courtesy The gentleman then offers his hand or arm
to his lady and conducts her to her seat which is the proper termination to every set of
Quadrilles (8 bars)"
 
 The "facing each other" would also seem to indicate that the couples are
crossing the set with their partners and not crossing their own partner.
