Unless someone could provide a cite, I would borrow from Reg. B here where it says the customer can choose the name they'll use with you, but it must be used consistently.
Just as we restricted customers from using dual signatures, I would hold them to one type here, unless they were paying some additional fee for your verification process. Still, I think it is more work than it is worth. But that is a personal perspective.
