Just some ideas, not a fully developed dance.

Three-couple longways waltz time

A1: 1-4: Partners country dance allemande (first half back-to-back, second half
         gypsy) into ...
    5-8: Circle six to the left

A2: 1-4: Partners *left* allemande
    5-8: Circle six to the right

B1: 1-4: 1s and 2s  CCW half-poussette
    5-8: 1s and 3s  CW half-poussette  

B2: 1-4: All set to partner, turn single
         All two-hand turn partner and fall back to sideline


Alternate version:
   Lines of three go forward and back, allemande right
   Lines of three go forward and back, allemande left
   

As above, then B1 is circle six right all the way around into
B2: 1s and 2s clockwise half poussette
    1s and 3s CCW half pousssette
