Here's another idea:
Instead of returning from the 12x12 turn directly to the 8x8 turn, the
sequence might be 8x8 to 10x10 to 12x12 to 10x10 to 8x8, etc. A sorta
in-and-out effect.
This would make the 8x8 and 12x12 phase every fourth turn, and the 10x10
every other turn. Pieces located on the edge of the 12x12 field would be
immobile for an extra turn.
