look at scm/modal-transforms.scm.  there's a scale parameter to some
functions; those are called from ly/music-functions-init.ly from functions
(e.g. modalTranspose) that still take scale as parameter.  there are
examples in NR 1.1.2 Modal transformations.  the scale is a set;
you would iterate through the music and replace each note for which
you find an enharmonic equivalent in the scale.

now as I write this, it feels easier than I thought, maybe I'll find time
enough this weekend to do it.
