This is something that's been suggested before.
There are two ways I can think of to achieve this in a way that would
suit you.
The easiest would be to extend the key/LED bus to an external connector,
and make a guitar effect style floor box that replicates the P3s
controls. That would probably cause other guitarists to run away
screaming. Which would be nice ;-)

The other way would be to add midi controllers for the main UI
functions, or possibly note numbers for these functions assigned on a
specified control channel.
I'll keep it in mind, and see if I've got the space once the rest of the
TBI is done.
