Hi Urs,
This is very closely related to the oft-discussed topic of “smart divisi” (for
lack of a better rubric) — see, for example, the threads at
<http://lists.gnu.org/archive/html/lilypond-user/2015-11/msg00794.html>, the
more recent
<http://lists.gnu.org/archive/html/lilypond-user/2016-08/msg00256.html>, and
the one that may be the oldest in the “modern [Lilypond] era”
<http://lists.gnu.org/archive/html/lilypond-user/2012-12/msg00425.html>.

Short answer: It can be “faked” by loading up the score with lots of individual
staves that french out when they’re combinable, allowing the [part-]combined
staves to appear. I put “faked” in quotes, because it requires the preparation
of lots of hats into and out of which the various musical rabbits are pulled —
it doesn’t (as you’ve outlined) take a single staff and do the splitting
automatically.

Once I get my two current commissions done and out the door**, I want to return
to my “Wither’s Carol” (the main inspiration for all of my feature requests in
this regard during the last five years) and use it as a demonstration of this
advantage. =)
Hope that helps!
Kieren.
** Perhaps ironically, these two commissions — a wind symphony, and a huge
piece (requiem kind of thing) for orchestra, choir, and soloist — would benefit
directly from this framework/mechanism, if it were already state-of-the-art. =\
