I've been thinking of something along those lines.... a parameter that
is used by \number to determine the digit set it generates.
I don't think that would help math, though; at least not the simple
implementation I was considering. Character access in math mode is a
whole different ballgame, and probably needs to be solved as part of an
overall review of math character codes, Unicode, \mathchar codes, etc.
I don't have the time (or competence) to dig into this area for now.
