Wasp half voltron

Trying to make Wasp's crappy Antman ally a bit more usefull, I've built around him a sort of voltron archetype.

Not 100% convinced about Iron man with only 6 ally upgrades in the deck. I'd like to run 2 more of them, but have no room. Maria Hill, Squirrel girl and Stinger can't be swapped out, cause Wasp is a quite fragile hero who can't tank villains more than once/twice a game in order to protect voltrons. Nonetheless Maria and Squirrel have blue printed resources and can be reshuffled several times due to Wasp's alt-ego ability. Any advice would be appreciated.
