The main problem with bringing back Yellow-Eyes is the fact that they would have to explain it in such a way that there would be some form of in-show lore to support it, something I don't think they'll be willing to do. I do love how they broke Cass in the last few episodes of the season, however, and I've always been a fan of the crossroads demon turned King of Hell, Crowley.
