I think Fraction could write an amusing triangle with Pepper, Hill and Tony. Pepper as the madonna he worships from the other side of whatever UST barrier they erected long ago, and Hill as the frenemy in arms who happens to look bangin' in her SHEILD suit (okay, wait, she won't be wearing it anymore but you know what I mean).

Hill has been Tony's dark mirror for a while -- same dark coloring, same hairstyle, even, (except for her inexplicable blondness in Invincible, sigh) -- so seeing them trying to cooperate as fugitives could be really entertaining. I can't say I'd like to see them have a physical thing, but, well, Tony's inability to keep his pants on is legendary, so I wouldn't be surprised. It's not like they'd fall in luuuuurve or anything -- neither strikes me as capable of it.
