I would love this… possibly with something similar to how EMH introduced Ultron.
What if WS, having regained some of his memories about his past, maybe turns himself in at the end of CA:TWS in order to atone for his crimes. He and Steve have some sort of "reconciliation" while he's being held by SHIELD, in The Raft/Cube/Vault/etc…. and then they reveal that Ultron or Ultrons is/are guarding the prisoners, including Rumlow/Crossbones, Zola (?), Abomination/Blonsky, Hammer (?), Aldrich Killiam.
Total setup for AoU-Masters of Evil thing.
