It would, though it would not be trivial, and also software written for 
the CoCo, that directly reads the keyboard, e.g. most machine code games 
  and Nitros, will expect the keyboard layout to be the CoCo one and not 
work :)

The electronic re-wire could be done with a patch board and a set of 
jumpers, or with some analog switches, I'm currently trying to get it to 
work with a pair of 4053s....it' sort of working :)

Cheers.
