If you use pairs, instead of lists, for the property overrides then the
override list is a standard alist:
\overrideGrobProps #'Accidental #`((color . ,red) (font-size . 4)
(extra-offset . (1.5 . 3)))
Seems like this might be able to be implemented in core LilyPond, but it's a
GLISS topic, I think.
Great idea!
