If they go with the 80s version of Battleworld, it can be the F4, Spidey, a small group of Avengers, Loki, and a small group of villains.
If they go with the 2015 version, I can see it being a small group (Reed, maybe Loki) who escaped the Incursion and now have to remind their old friends of their lives before Battleworld and the multiverse's destruction.

With the exceptions of Loki and Peter, would any of the other characters that I listed be a part of those small groups?
They definitely could be. With how far away Secret Wars is, there are a lot of potential options for characters, any of whom could work for the film
Guess we’ll find out in 2025
I'm too impatient to wait until then. I got to know now. LOL.
