Is there some way to "template" commands for interpolation with gdb.Values?

That's pretty much what I would have tried.

I didn't follow this part.  Can you just use .address in your implementation?

Definitely, it's just a question of deciding what would be most helpful
and then, of course, someone actually implementing it.

A different approach would be to parse the user's input.  This is what
Duel did.  However I suppose that is in some conflict with your goal of
being language-agnostic.
