You actually have 2 problems there:

1) How to make X or Wayland differentiate between the 2 input devices,
which at some layers will just appear as the same thing (8 on one will
be the same keysym as 8 on the other)

2) How to make X or Wayland map the keys to different keys (taking into
account #1 above)

#2 is pretty easy in X.  My hunch is X will make all of this easier
rather than Wayland, mostly because no one has thought of all the corner
use cases for Wayland yet.  So maybe find an X distro for the Pi.
Also, wacky use cases for X should be numerous on the net forums,
whereas Wayland is all brand new.

#1: I have no idea, but could look into it.  I have not dealt with a
layer in X that would handle this, though it probably exists.  One that
would let you change the keysyms based on which input device is
operating?

One would think this would all fall under "accessibility", because
there are all sorts of wacky devices for those with impairments, and
you could easily have more than 1 of the same device (say, foot pedals)
that you want to have do different things.

In any event, it almost certainly will require some intense conf file
editing.  I'd be shocked if there was a gui for any of this.

Cheers!
P.S. Come out to a meeting sometime, we miss you Montana!
