No, don't delete the project from launchpad, just change the part that says "Which bug tracker do you use: trac, python.org, bitbucket, launchpad" to say "bitbucket" instead of "launchpad". If "bitbucket" isn't one of the registered options then you can just say "None of the above" and give the URL to the bitbucket project I don't remember exactly how the UI works, but if you give me admin privs I'll do it.
