Interesting. There are a couple possibilities, I think.
My current favourite, \variant[something], is essentially a convention
that's built on top of the font synonym mechanism. There's an example
given at:
<http://contextgarden.net/Font_Variants>
...but I haven't done a proper write-up yet.
basically, you declare a variant set for a (Serif/Sans/Mono) family:
\definefontvariant [Serif] [exp] [-Expert]
% [fam] [call abbrev] [synonym suffix]
And then you create font synonyms for each of the possible seven
SerifBlah-Expert fonts that would be called, e.g.:
\definefontsynonym [SerifRegular] [AndulkaText]
\definefontsynonym [SerifRegular-Expert] [AndulkaTextExpert]
\definefontsynonym [SerifBold] [AndulkaTextBold]
\definefontsynonym [SerifBold-Expert] [AndulkaTextBoldExpert]
Where the AndulkaText font resolves to your st2 encoding, and
AndulkaTextExpert is in your st3 encoding. (I haven't tried this trick
with different encodings, but it *should* work!)
You can then call the proper variant with {\bf Hi there \Var[exp]+}, or
create a level of indirection with your \textplus macro so that it calls
the [exp] variant and the glyph together.
The Storm fonts are beautiful. Sigh. Have fun with them...
