What would Bucky or Loki have to offer as the hero? All of their stories have been covered in the other marvel movies. What have either of them done on their own? They just basically fight avengers. I could see black widow doing some pre avengers stuff and I could see quicksilver having a lot of storylines outside of DOFP the storyline (I haven't seen apocalypse yet).
I don't know much about Bucky, but they could have an interesting plot with Loki as the antihero. It would just be skewing the perspectives a little so that Loki is shown more often and with more explanation, while the Avengers or other antagonists are shown less frequently, and with the air of mystery usually given to antagonists. Just for a change.
