Checkers with chess pieces?

[ChessCubesAndCode]

I noticed that you need more chess pieces for chess than checkers for checkers. I understand that chessup could make a little less money with this feature but purchasing checkers would still be nice for more authentic playing. What if you could set up checkers with unrelated chess pieces of the same color? Kinged pieces would show on the screen. I think a lot of people would really appreciate this feature (and folks like me who lost 3 of their checkers pieces, can you buy replacements?)
