That goes without saying, but I thought the request was for the
"normal" mouse face to be able to do that.  It sounds a kludge to me
to ask that each button uses a different value of mouse-face, since it
means someone should construct each button by hand, and not generate
them by generic code.

But if using different face values is a good-enough solution, then
sure, why not.
