I look a look at the character set specimen for Cambria Math at
and near the bottom of Page 2 are what seem to be the large prime

I have no idea how to get at these glyphs—they do not seem to be in
Unicode or in the font’s PUA—but if they can be used they might make a
more natural match to TeX’s primes behavior.
