The problem is that this will deal with the CV/Gate to the M cards, but 
there's other places that use the note data from the KAS that won't be 
updated correctly.  For example, the KBC boards use the note/octave 
codes to generate the Brilliance & Level High/Low.  This really has to 
be done in the KAS chip, so it would have to be replaced by a PIC or 
FPGA.  Of course, if you're going to do this, you'd also implement MIDI 
in/out, different voice assignment mode (low-note priority, etc), and 
lots of other stuff.  I've thought about doing this, but then I got 
better :^)
