Actually, I had a similar case that I wanted to do in TeX recently, but
couldn't figure out how.  In the Lambek Calculus which I used in my
dissertation there are left and right slashes that do *not* mean
division. Their corresponding 'multiplication' has a black bullet
notation (probably meant originally as a bold multiplication point), and
therefore using a mathvariant=bold of the slashes would have made
excellent sense in that notation (indeed, as I said, I actually went and
tried to do that by wrapping a \mathbf around the slashes, but that
didn't appear to work, so I just gave up on that idea).  Since the
meaning of those slashes is different from regular division and
set-difference, say, the mathvariant solution would have been quite
appropriate by your standard as it was meant to underscore a deeper
semantic distinction.

This is just meant to help clarify the situation a bit better, but in no
way as an attempt to solve the actual question itself, which I gladly
leave to the experts.
