I'm surprised that it worked because we do math deep down in a different
way than you (probably) assume. Anyway, your definitions are not ok as
they refer to the wrong family. Also, you need to refer to the lm fonts
as these are the cm replacements.

These old fonts with glyph widths that cheat assume an old math engine
(with respect to kerning and italics which are fundamentally different
in opentype math) so there you need to compensate yourself.
It's proabbly easier to use the math font fallback mechanism and map
that range to some other math font.
