I am investigating a very similar project. I'll prob. use a 16F84 and have
probably 32 knobs but the basics are the same. I would be interested to know
how the MIDI merge goes as I was considering adding such a function (or at
least have MIDI in for Sysex config. dumps).
The main problem I can see is dealing with too much data overflowing the
system.
How do you mean merge?
I would suggest that simply merging your data into the incoming MIDI data
with no logic could create problems. Particularly in relation to sysex
dumps. I think you would certainly have to watch for sysex dumps and cease
your MIDI out when a sysex dump was in progress.

I would be most interested to know how it all fits together.
Tom.
