Bendis writes Ultimate Spiderman set in te UU whilst chronicling the adventures of the X-Men in the 616 so I fail to see the correlation.
It's not as if I was suggesting that Hickman write 616/UU Avengers tales simultaneously.
As I mentioned in my previous post, my primary interest in seeing Hickman write more books set in the 616 once he's completed his run on the Avengers, is down to the respect that he has for correct characterization, continuity and world building that realistically incorporates what came before whilst creating additional layers that add nuance to the pre-existing concept.
