Ik they’re more Avengers-oriented, but my vision is that they’re primarily composed of Captain America villains at the beginning, such as Sidewinder, Baron Blood, Batroc, maybe a new Crossbones, plus maybe the return of Justin Hammer. They’re all organized by The Leader to help with his plan of revenge.

However, maybe Justin Hammer decides to form a new Masters team following the events of Brave New World and it consists of more villains such as Radioactive Man, Absorbing Man, Abomination, Spymaster, etc.
What if The Masters of Evil were introduced in Brave New World, and were led by The Leader?
