Xbox Content

So you're limited to all the content purchased with the breakingben profile (attached to mmueller07@hotmail.com)

You can't permanently transfer content from one account to another however if you had a 2nd profile on the same console, you could share everything that's attached to the breakingben profile with the 2nd profile (a new one you made).  Then all future game purchases would be attached to your new profile while still letting you play anything under your new profile as long as the breakingben profile is on the console.
