What can be used to dissolve a thin film of cured polyimide.

Not much.

OK, if nothing dissolves it, what will de-link it? Will UV light do
it?

It will damage it.

Could strong UV light be used to soften epoxy so as to be able to
get
better adhesion to a later layer?

No, but 24 grit paper and elbow grease will improve the mechanical
coupling of old and new.

Yup, I didn't see the original post but Epoxy, when used and prepared
for properly will do a fine job without softening the under layers of
resin. Like I said, you are not going to get a chemical bond, just do
the mechanical bond with care and you will be fine. You will get full
use of all of Epoxy's wonderful properties. No need to get all star wars
on it
