If you like this idea of embedding a bug-tracker (and eventually the code review) within a DVCS, I'm working on a project[1] that does that for git.
When I started exploring this I registered the gitbug.org domain - would you be interested in using it for your project?
I have a bunch of git-bug.tld domains so I guess I'm all set already?
I'd be curious to see your project. Maybe there is a good idea in there? In any case, you are very welcome to join the party.
