Well the example I sent you doesn't do that (it could perhaps if you
set the second (mirrored) staff as a voice on the first staff and ask to
merge stems ... don't know if that's possible). My example is for where
you want a new staff, derived from the first one with the music an
octave lower. It turns out that (as so often) your question turned up a
wrinkle: the Transpose Staff command is actually transposing the voices
on the staff. I've now added a real Transpose Staff command, and moved
the current command to the Voices menu. You can now mirror the music and
then transpose the staff (there was a technicality making that tricky
using transpose the voice).

Well, no, if you want a part to print out in octaves throughout then
writing a script to insert the note at an octave lower would seem
sensible.

(ANS::AddIntervalAsChordnoteFromLowestUp 'p1)
(d-OctaveDown)

does what you want, I think. (There doesn't appear to be a 'p8 for
adding an octave so I added a unison and shifted it down an octave)
