Remap IO pins to step/dir/en on Duet3

Re: Duet 3 with E3D Toolchanger setup - small Stepper Motor question
@dc42 you previously said the following in the above linked topic:
It should be possible to use a SammyC21 and 2 or 3 stepsticks to drive some additional small motors.
I see how you can use SammyC21 board as a tool/external stepper board but is it at all possible to simple remap otherwise unused IO pins on the Duet3 (or Duet 3 mini 5) to become the step/dir/en pins for any desired motor axis? I know the Duet3 will have plenty of spare IO that I won't be using and if I could just remap things it would allow me to use hyper servo/steppers with external drivers without requiring yet another expansion board.
Is that possible at all? -
Unfortunately it's not as easy as remapping. Recompiling the firmware would be required.

Ah - boo. Ok.
With the SammyC21, how hard would it be to modify that firmware to let it control 4 external steppers?
