face-spec-recalc and face-spec-set come to mind, for example.

I asked whether the higher-level functions can do the job.  If they
cannot, please explain why, and please provide specific details about
the difficulties.  Answering my question by another question doesn't
help, since I'm sure I don't know enough about the job you wanted to
do.

There are many documented functions that set face attributes in
various forms and for various sets of frames.  My question is
precisely whether any of them can do this job.  If not, perhaps we
could extend one of them to support whatever you need to do.  That'd
be an alternative to renaming face-spec-set-2 and making it public.
