Would pick up Cassie/Stature in her original look. Also, have the MC2 Stinger which holds up pretty well so don't feel a need for an update.
Wouldn't mind more MC2 figures, however I think they're pretty unlikely given the lack of new comics material. MC2 was such a breath of fresh air in terms of future timelines. It's the only fleshed-out Marvel future that isn't some dystopian nightmare. It was fun too, in the sense that it depicted real things that happen to people as they get older. As an example, loved that Flash Thompson ended up being a high school coach/gym teacher but was also now a balding guy with a middle-aged paunch.
