I don't know how difficult and how much work this would be but as a user
I would like such feature very much. I faced a related problem with my
ergo-movement-mode [1] which, for example, uses

          i
    M-  j k l

keys for basic cursor movements. The mode actually doesn't bind them
directly but relatively. That is, M-l is bound to

    (lambda () (interactive)
      (call-interactively
       (key-binding "\C-f")))

so it executes whatever command is bound to C-f. This works in all major
modes automatically but the problem is that I can't rebind C-f to
anything. The default Emacs global keybindings are not practically
customizable.
