Do you have an xbox gamertag account linked to the Bungie.net account in question, or do you only have a PSN ID linked? If it's only the PSN ID, I don't think you can directly swap to a different PSN ID. In that case, try linking a gamertag account (it can be a free xbox silver account), so you have two authentication methods linked, then unlink the PSN ID you don't want linked and add the PSN ID you do want. [edit] if the account you're trying to link is banned by PSN, I don't know if that can be an option for your Bungie.net account. Can you still login to it on the PlayStation website? If not, it may be disabled from using the PSN authentication services as well and may not work for Bungie.net login [end edit] Just be careful when unlinking accounts, as a Bungie.net account that ends up with no linked authentication methods (PSN ID or gamertag) can't be logged into anymore to add another account.
