Interesting!

Driven by curiosity, I put this plugin together. You could try installing and activating it: it should make it possible to use [topic-author] from both the new reply subject and body.

It doesn’t do much else, though it could itself readily be extended (but perhaps the better course of action would be to see if the original author of bbPress Notify can make a change there or, if it is no longer receiving updates, fork it).

At any rate, I hope this is helpful, if only as a starting point 🙂
