How about a Copycat dance. In a square or small circle (to suit number of dancers. You can make up the first 16 bars worth (turn partner, turn neighbour / do-ce-dos etc.whatever).
Bar 9-16 couple 1 steps in and the others circle left & right.
Bar 17-24 1st couple does something (maybe a swing in a particular hold, maybe something different)
bar 25-32 the other couples copy.
I'll pm you another that I use (since I don't like putting other people's work up in public)It's called Jiggilywig by Colin Andrews annd is very simple until you actually dance it, when it's completely disorientating.
