I don’t know anyone that has successfully done it (at least I can’t remember a post or anyone bragging about it), but I created a TRAC ticket for a future version on this issue:

https://trac.bbpress.org/ticket/579

You might be able to play with rewrite-rules.php in the /bb-admin/ folder to get some direction on what to change in the meantime to play with it, but I don’t believe it is pluggable (for a plugin).
