You should be able to get a new passport issued (after surrendering the old one) if you make a claim of "substantial change of appearance" since the first one was issued. I know this works in India and Canada, so I would assume a similar situation exists in the US. I know someone (a Sikh) who did this after he gave up wearing a turban and went cleanshaven instead - he had to get a notarized affidavit that he was changing his appearance and that he was the same person. They then cancel the old passport and issue you a new one with the same validity after paying the appropriate fee.
