oh yeah that would be difficult and next to impossible , to set up, because of repeating letters on the board I would say that was a fools errand. Sorry about that but the game is absolutely perfect in it's concept. The game play is easy to get used too. I would leave it as is.
Just realized that because the letters do not need to be next to each other to spell words ? so the keyboard would actually work.. I been playing this game a fair bit.
