Also, Secret Empire was originally just going to be a Captain America arc, so it wouldn't be the first time he went and changed a big development in a run.
I believe the current list is:
Mary Jane, the Fantastic Four, the New Avengers (Hawkeye, Mockingbird, Iron Fist, Spider-Woman, Captain Marvel, Wolverine, Jessica Jones, Luke Cage, the Winter Soldier, Doctor Strange), Kaine, Julia Carpenter, Jackal, Captain America, Carlie, Miles, Anna Maria, Miguel, Anya, Doc Ock, Silk, Spider-Gwen (and any of the other Web-Warriors, obviously), Prowler, Ben Reilly, Teresa, Jonah, Norman(forgets again), and now Felicia.
