You can change the e-mail address used to log in on the current account to an e-mail you don't use. Then you can sign in with the e-mail address you currently use (as it's now, not linked to that Bungie.net account) and you will be prompted to create a new bungie.net account. That's what I did when I changed my log in.
You can do this at Passport.net.
