Look at fnts.doc and see which families you can do without.

It is to fit all of character+family+class selectors into a
16-bit math code.  If you change the size of the math charcter
code in TeX then all packages/documents (like AMS) that assign
them fail.

Make a graphics file from the glyph and include that?

Are you using sans-serif math characters?  If not then you should be
able to comment-out three families from fnts.tex.  For just more sizes,
I'm pretty sure there are plenty of alternatives.
