The Julia Carpenter Spider-Woman is awesome. I think it would be cool to do an update of Jessica Drew.
I think a mini version of Scott Lang Ant-Man would be perfect with Jack of Hearts.
Vision, Jack of Hearts, Spider-Woman, Quicksilver, Scarlet Witch, Lionheart. There are still a ton of Avenger characters. I mean it would be cool to get a little Ant-man with an updated Ultron.
