Hi Louise,
Here are some more ideas:
Alamo Triad
http://www.kempt.net/~entropy/zcs/zcs-part-4.pdf
This is a three couple progressive contra dance - not sure if that comes within your
parameters as the three couples are in a triangle.
Olympiad (by Ian Nichols and Julia Dean) is a Sicilian Circle for Trios with Stars, Heys
and a Right-Hand-High-Left-Hand-Low
Not sure where I got that one - e-mail me if you would like the instructions.
Double Take is a dance for Trios, but they are in a Square - again not sure if that is
relevant to your situation:

They are all fun dances that I call regularly.
Happy dancing,
John
