There are three approaches to this:
1) Define note names programmatically. You have a scheme interpreter at
all stages, after all. I do this for tripod notation.
2) Have commands to apply accidentals. This is a solved problem as
well. I have JI Sagittal support where you specify the pitch as a ratio
relative to the tonic.
3) Have chained accidentals, like for Extended Helmholtz JI. So you
have a \sharp command that sharpens the pitch and adds a glyph to the
accidental string. This way, you can have an open ended set of
accidental strings for an open ended pitch space. I think this has been
implemented for the visuals but not the sound. There are problems
getting both to work together.
