> I didn't like the idea of a queen on one board capturing the king on another board as her first move

If you did want to experiment with supporting cross-board captures, an alternate way to address that could be by rotating the board 180° every other row, so that white pieces have other white pieces behind their home rank.

oh this is a pretty fun idea! If I decide to keep this one around for a bit maybe I'll play with doing this after wiping the board

This would be fun!
