I would imagine the problem is the same one that I mentioned above in
the thread.  Calling ly:grob-extent to determine the printed width of
the staff causes side-effects.  I'm sorry, but I don't know of any way
to determine the staff width without running into this problem.

It would be relatively easy to alter the function make-page-stencil in
scm/page.scm to do what you want.  The stencils of the individual
systems are already made at this point, and it's just a matter of
moving them around to your liking.  Unfortunately, this requires a
change to program files.  I've had no luck copy/pasting code from that
file into the LY file.  It will be a lot--if it can even be
done--because so much of it is non-public.

Did you get a good result with the markup-based solutions?

Best,
