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.
