Not going to help since the Tie_engraver and Slur_engraver live at Voice
level and won't see those overrides.

I think specifically with respect to piano music where the
Voice/Slur/Tie relation is a lot more fluid we will eventually have to
come up with something more flexible with regard to how properties and
engravers are tied at the context level.
