Reading this, it's extremely unclear what you actually want to happen.

Again:  Give a real world example of a UI problem using your proposed
feature.  Not only will that help justify it, it will clarify what
exactly you think it should do.

(The example I gave causes the given face's display to change _during
the binding_ -- I used a call to read-string in my example because
that causes redisplay and user interaction within the binding; the
display of the given face changes back again after the binding ceases
to be active)
