Ok, I think we can forget about 16x16 for now. I tried ChessV with the 16x12 Double Chess... OUCH. It barely works at all. The branching factor is just too high. Even the opening position has 72 legal moves (compared to 20 for Chess). I suspect midgame positions could easily have over 200 although I didn't get that far.
More than 16 files is also problematic. It would increase the size of a data structure that stores pawn information.
