I wonder how her relationship with Tony would be. Would it be as antagonistic as his relationship with Steve?
Given the relationship between Howard and Peggy I think Tony would treat her like an honorary Aunt, he have probably grown up with stories of her heroics.
The one story I would love to see in Season Two is if the Avengers had been formed twenty five years earlier in 1987. With Peggy Carter in the Nick Fury role with Mar-Vell, the Ancient One, Yondu, T-Chaka, Hank and Janet Pym and a teenage Tony as members.
Well, there's no Winter Soldier to take out the Stark's unless Hydra still takes over SHIELD and has them killed, and Howard built Iron Man before Tony did, so that might have big multiverse implications.
