yep.

Yes. shape is just a proposal.  Probably it's better to use glyph (a
string), because that exists already.

Yes - however, I would simply use a number:

 notehead-0-solfa-3 is fa
 notehead-0-solfa-4 is sol
 notehead-0-solfa-5 is la
 notehead-0-solfa-6 is mi

that makes for easier computation, since you can do subtract tonic
from the pitch, to get that part of the name.

No, but you could have the print function do lookup, taking into
account the #'glyph setting and the direction of the stem.
