Yes, something like that.  But the major work would be to create a
sensible widget that allows people to customise the keymap in question.
It'd be nice if it displayed a graphical keyboard in a buffer, and you
could click on keys to specify what they should output.  😀

Or something simpler, for instance a widget where you ask the user to
enter a chord/key stroke, and then prompt what command to bind that to.
Or...  something else.  Many possibilities here.
