its only possible with an RGH or JTAG console as a non modded console will check the DLC you try and add and thus you would get banned assuming you even get it to load the unsigned code as its called.
with only a modded CD drive you can replace characters and only replace the non DLC guys.
if this interests you head over to smacktalks.org. they have people who do this stuff....but again you will never an RGH or JTAG console. you can do it yourself to an xbox you got lying around or spend 200-300 roughly for one.
