Yeah, you can do this.
I actually designed a 32-key keyboard last year. Even built a proof of
concept proto...I think it had 4 keys or something. I used a similar
hardware concept which could have been expanded to (I think) 256 keys,
and the software would have been pretty simple to implement. (never got
around to that...) I'll try to dig up the proto, but I think I cannibalized
it for parts. :(
