What about maybe using a water clear urethane skin and a thin nylon film behind,then mold together? Can you print on nylon film? Would it survive?
Just tossing out ideas... might not be good ideas but ideas none the less!
Look at the gas pump keypads - they are perfectly flat w/o bumps. What if you made a thin spacer to keep the contact film off the board and when the key area was depressed it made contact - you know? The face of the keypad could then be made flat and could open up a few more options.
