Yes. Use of sans-serif is not at all uncommon.
[In logic it is quite common to see inverted sans-serif
A and E as quantors.
I take Humphreys, Linear Algebraic Groups from the shelf
and see that he uses sans-serif K for a field, sans-serif k
for a subfield.
Next to it, Huppert, Endliche Gruppen, uses sans-serif italic K
for a field, sans-serif italic V, W for vector spaces,
sans-serif italic P for projective space,
sans-serif (non-italic) cyrillic ii for the set of all soluble
fraktur A invariant p'-subgroups of fraktur G
satisfying some technical condition (etc. etc.).]
Indeed, a mathematician will tend to use *all* available
fonts and symbols (that he thinks the reader can recognize
and distinguish).
The STIX proposal does not contain all symbols necessary
to typeset the just-mentioned treatise by Huppert.
