Hi again, It seems like there is not an easy or straightforward way to do
what you want.  (Although I'm not exactly clear on what you want to do.)

The properties set by \clef (clefGlyph, middleCClefPosition, clefPosition,
and clefTransposition) are context properties (as in the staff context) and
not grob properties (as in the clef grob).[1][2]  As far as I know, the way
to access such context properties is by creating a new engraver (in Scheme)
that is added to that context, one that can access those properties and do
something with them... but I'm not sure that will help in this case.
