Actually I think you can buy one game from the store and use its klicensee to encrypt disc content of another game, then you should join the header with ECDSA signature from the original game and encrypted disc content from the another game. But you should carefully choose a boilerplate game because its size should be bigger than size of the game you want to reencrypt, so you can append padding bytes and generate the corrected LIMG segment. I think it should work on OFW too because the ECDSA signature covers the header only and not the data and header stays unmodified with the method above.
