I've never tried it, but the idea i was having the other day was for a ring of 8-10 cameras suspended just above head height that descend under gravity while the subject stands still in the middle.
The descending cameras could also take a helical path downwards to simulate a more evenly distributed array.
I just think it would be tricky standing still enough on a rotating turntable, whereas the descending cameras could be moving very fast so long as the flashes can keep up.
