I think the answer to the other items is no.

thumb is a Script grob, not its own grob.  Fingering is its own grob.  So I
think you can't add all of the grob properties to the script alist.  All
those other properties are set in the definition of the Script grob, in
scm/define-grobs.scm.

If we want to have \thumb become a Fingering instead of a Script, then we
should change it in the parser to be handled by the New_fingering_engraver.
