Passing powers around would make the game rather complex, and difficult to comprehend. Though the rules for such 'passing' should make this a rare event, and it should be consider a turn in itself.

Might I suggest that such 'passing' could be accomplished by allowing the power to move according to its movement to another friendly 'stack'. Only one disc would be allowed to do this. And no other move would be allowed during this turn. And a piece would not be allowed to be reduced to a Pawn.

Though the 'passing' of powers might create a potential draw, where players merely move discs from one stack to another. So the restriction that a player not be allowed to make 'passing' moves back to back might be applied.

Another 'passing' rule' could be when a capture is made. Any extra powers might be moved to other friendly pieces. This could also be restricted to their position according to the capture, the powers would move from this position, according to its particular movement, to the friendly stacks. This could be seen as a 'reward' for suffering the threat of this captured piece. ;-)

But I think that such 'passing' of powers will be un-necessary. The game might start with rather weak pieces, but it will quickly build up some very powerful ones. Several having the ability to perform checkmate alone, even if against a powerful King.

Also, there might be the introduction of new movement powers, like the Camel. Just assign a unique color this movement power. There are several vacant cells on the starting second rank available for such new pieces.

I am working a Zillions implementation for this game. The hold-up is the planar moves. These tend to really bog down the engine. I'm working on some new code which might help.

Hey, Larry, nice method of passing powers around. [Easy and inexpensive for face to face; three checker sets and a little white, blue, and yellow paint, and you're in business, once you've made the board. :-) ] Have you considered allowing pieces to voluntarily pass powers around? Given that you've separated the pieces and their movement powers completely, you have a fertile field for playing with passing movements around. 
The simplest and most interesting way might just be to allow each player to remove one checker from one stack and add it to a neighboring stack after they take their turn [and before the other player's]. Letting players swap a movement checker to a neighbor, then move a piece would probably not give the best games, but they would be quick. 
There are a lot of ways to add to the game, but too much complication probably means you'd have to buy more checkers. You might look at allowing pieces to move through each other, merging and separating in a turn, and allowing movement checker transfers during this. This could add a little more excitement [and complexity] without adding more checkers.
When's the Zillions available?
