If you are really smart you could right a protocol to allow the main PCB to talk to another micro over the 4 digital pins and by doing that add virtually as many analog/Digital inputs as you want.

i wish i was really smart, lol

incidentally, sparkfun also has Monome style buttons. those could be cool for the bank buttons as well...
