Would this be one of the best feuds in WWE history(two guys who actually dont like eachother)?

Ok, so it may be a rumor. But, I heard Cena & Ron Killings dont like eachother. And this is a scripted thing, they really have a beef. So, what if when/if Killings debut they trade someone from Raw(possibly Umaga). And bring on Ron Killings to attack Cena. Then they heat things up even more by letting them shoot on eachother(I think shoot is the right word, correct me if I am wrong). They just let them talk about eachother, with no scripts involved. Then, Cena goes back to the "gangsta" gimmick and uses his old theme. So, Cena and Killings have their feud. And at SummerSlam it would be Cena vs. Killings in a street fight. Do you think this would be a ncie feud? And how long would it last?
