Using a matrix keypad for second generation consoles

Has anybody ever considered integrating one of these 3×4 matrix keypads into an arcade stick for console such as the ColecoVision, Intellivision, or Atari 5200? I'm considering hacking one together with a keyboard encoder, but surely there are more elegant solutions.

Having the MiSTer recognize it as a controller rather than a keyboard would be preferable, but is it possible to have that many buttons on a single controller? Are there even any joystick encoders that support more than 12 buttons?

Yes there is. The Ralphnet and I think Demonbytes SNES to USB adapters can accept the SNES NTT Data Keypad and all it's inputs.

I've used the Jaguar Pro controller replica setup with my BlisSTer.

I just checked and I'm able to map all the buttons, including the 3x4 keypad.
