I don't think Bendis would be in the mix because he lacks editorial experience, Mark Waid is one of the few creators who might have been considered, but between his outspoken online persona, the fact that'd he'd likely be considered too old guard, and his 3 most recent books Avengers, Champions, and Black Widow, while maybe not total flops, have certainly underperformed for the resources Marvel invested in them, especially Champions, that Marvel has to pay that RPG company for to share the rights to the name.
