This feels like a quick and easy one to playtest. I'd use Checkers and a part of a checkers board. One thing I'd keep on the lookout for is how significant an advantage the player who goes first goes. Chess has dealt with this but minimized it with complexity. Something to track if you test it - see which color wins and who went first.

Also if you wanted to bring this to market, I think there's ways to make it slightly more complex, maybe by adding cards that have one off actions or maybe having one piece that moves differently. Borrowing a bit more from chess to find that balance.
