They are trying with the New Blood/ECW Original storyline, but aside from Burke and Punk interacting there is nothing there.

They need a stable much like the New Blood in that they are young up anc coming talent banded together. If they can tweak the New Blood just a little bit that stable could be huge. Expand it to have members in all brands of wrestler's tired of being "held down". Punk and Burke would be great ECW members, while a guy like Matt Hardy could be the older veteran of the group. There are number of superstars from RAW/Smackdown! that could join, or they could keep it rather small like Evolution was.

Right now that is really the only stable that could work. A stable of only established stars would be just another re-hash at this point and would not last very long, seeing as stables should push newer talent to the top of the business (the 98 run of DX and Evolution being the prime examples).
