Ditching Vbseo for Friendly URLs

[Akyeame Kwame]

I'm looking to ditch vbseo in favor of the friendly URLs due to server overload vbseo causes.
However, vbseo generates

forums/my-forum-name/64854-my-thread-name.html

while friendly URLs (mod rewrite) generates

forums/threads/64854-My-Thread-Name.html

Is there a way via .htaccess or otherwise to make the friendly URLs pull my forum name as vbseo does rather than the generic threads? I'm looking to avoid link rot as, right now, all traffic from previously high indexing threads are being redirected to forumhome.

Any assistance would be GREATLY appreciated.
