I think that talk of Barrett as a world champion is a bit soon for me.
Personally i'd like to see Miz lose his US Title to Daniel Bryan in some way. I would be happy for Barrett to feud with Bryan and eventually gain the US Title.
At the same time as this i would have any two of Slater, Gabriel & Sheffield (Gabriel & Sheffield would be my preference) win the Tag Titles.
They could also take some of the new crop under their wing and slowly a rift could form. Its been done before but it could birth some really good talent.
