If there's some intuitive reason for choosing different 
logical equivalents, perhaps that should be reflected in 
different pitch alterations anyway.

Yes, sorry that went privately.  I forgot the "shift-ctrl" 
to reply.  The idea is you can only have one set of 
quartertone symbols at a time, but you can use a \tweak or 
\override to switch between sets.  I have proof of concept 
examples for pure/mixed Sagittal.

The cheating looks fine until you want to do transpositions. 
 Transposing C up-a-quartertone up by the same quartertone 
won't give C sharp, for example.  If you think it should 
that's an indication you're treating quartertones equally, 
of course.
