That's almost certainly true; I don't know what kind of math you do so
I can't be sure the symbols you need are in Unicode, but certainly all
the math symbols I can remember are in it (I admit I haven't memorized
the symbol tables in the TeXBook.)  So I think the odds are quite high
that you can rip out of x-symbol all of the charset code and glyph
definitions, and just use the macro/character swapping code and input

That's a guess, based on the fact that recent versions of xelatex
uglified documents derived from my older templates until I set the
parameter that enables the traditional double-APOSTROPHE,
double-GRAVE, and multiple-hyphen ligatures again.

It's certainly possible to do this, but since these are all going to
be multibyte characters you'd need to do some really obnoxious
gymnastics with active characters.
