I don't know how it would work but if I had a say in the matter, I'd want to specify which bbPress forum will house the blog posts. Each post becomes a topic within that forum. Then the comments become replies. Meanwhile, the rest of the forum continues to act on its own. If it worked that way, I don't see how it would be thousands of per-post forums.

One forum, new blog posts would be new threads and comments would be replies to the thread.
