Some guys out grow the "repackage" process. It usually worked when one guy cam from another company, because most casual WWF/E fans did not watch the competition, that is until the Monday Night Wars. So a Mark Callus, Diamond Stud, Vinny Vegas could come to WWF as Undertaker, Razor Ramon and Diesel. Kane worked because no one (unless you're a real fan who pays attention to body structure and move sets) knew it was Issac Yankem or fake Diesel. Nowadays, WWE really likes to insult fans intellegence by bringing guys like Ryback, Albert, A.W. in and hoping we forgot these guys were on TV not that long ago. Sure, WWE would like us to forget that Ryback is Skip Sheffeild. They also know some "smart" fans know that Tensai is Albert, but they don't mention his old name, just that he was a "Former WWE star that went to Japan". WE ARE NOT STUPID!!! I think that when Hall and Nash went to WCW and used their real names, (because Bishcoff's idea to make his wrestlers more real), kinda opened up the kayfabe floodgates and when guys went back and forth to the two companies, they were gimmick-less and fans already knew the difference.
I don't know why the WWE tries to bring guys back without fully explaining their past. I really think they think we are stupid. Youtube is a very useful resourse for past information!
