Yeah, appears to be the correct range. Couldn’t test with Lucida,
though.

But if there’s a math font, I’d go with the example that Wolfgang
posted; alternatively just wrap the converter into \mathematics:

········································································
\unprotect
\def\math_greek_characters#1{\mathematics{\greeknumerals{#1}}}
\defineconversion [mathgreek] [\math_greek_characters]
\protect
········································································

etc. It will depend on your choice of math font whether you get
italics or upright glyphs.
