I think you underestimated the meaning of:

    I'm really not familiar with the widget code

I put "really" before the "not", because I know very little about
that code.

I suspect thinking in terms of "activation/deactivation" will not
be helpful.  We should look at the code which does the insertion of text
(which presumably happens, among other things, upon deactivation).

> Though that seems pretty ad hoc...

If needed, we might be able to make it less ad-hoc by defining
a function for the purpose of (re)inserting text inside an
existing widget.

> (and would resetting the :from affect the fontification?)

It'd be up to that new function to make sure things work as they should.
