OK, if readline as it currently exists doesn't offer the feature you want,
why not take a shot at writing it? You might find that others like it as
well, though none of them have spoken up so far.

I would argue that neither of those -- and certainly not the latter --
constitutes `normal text processing' as readline is most often used.

What you've done here is bind backquote to a non-existent function and the
three-character sequence `T'`A'`B' to `B'.
A few minutes of testing with an inputrc consisting of
"`": complete
TAB: self-insert
seems to produce expected behavior.
