I didn’t read the whole thread but how to deal with different clefs?
For example, in a choir a tenor is notated with \clef "treble_8" but a
tenor/bass combined staff with \clef "bass". This case isn’t a problem
because lilypond uses the clef of the bass voice (two \clef events at
the same time, second one is used). But maybe there are cases where
you would want have the clef of the upper voice (f. e. horns in
octaves, one in treble, one in bass clef, combined in treble clef with
ledger lines for the lower horn)?
So? The whole point of the layers is that you (more or less fully)
prepare both a split and a combined version and LilyPond then picks the
right layer. Split and combined layer don't need to have the same
source and/or overrides: you can use an alto clef for the combined
version and violin/bass clefs for the split version if you want to.
Of course you will _largely_ want to share the same source, and tags,
variables, and parallel music expressions will help with that.
