With proper lines: 1s and 2s each Partner Right allemande 3/4 in the middle of the set. Take left hands with your first corner, and there's a momentary long (and probably crowded) man-woman-man-woman-etc wavy line down the middle of the set; men facing back to the gent's proper side, women facing the lady's proper side. Everyone Left allemande first corner once around, back to your partner. Partner Right allemande just half way. Second corner (again in a long wavy line) left allemande once around and you're back to your partner. Partner balance and swing (if there's room for the simultaneous neighbor allemandes, there's room for simultaneous partner balance and swings). Now if you called Everyone go down the outside then inside, turn, contra corners; it'd probably be a total chaos cluster, as folks would be more likely to lose their reference points/people in the initial hijinks. But I do think that simultaneous contra corners theoretically works with slightly modified allemande distances.
