Fox might want to stick to what worked for them before - meaning more films to the characters we already saw before and not do something completely different like X Factor, X Force, Deadpool.
But why couldn't they take some of the existing characters and transform them into one of these other teams. That way you get both, characters the audience knows, and an expanded universe.
At the same time they can introduce some yet seen characters and then put them into these other teams/movies. Just like they're doing with Gambit (even though we kind of saw him before).
They could easily take Quicksilver now, and put him in say X-Factor. They could easily introduce some other characters, like Polaris and Forge, and then have them in X-Factor, as a government team. Add in one or two new characters, like Strong Guy and Wolfsbane, and there you have it!
Also, you have to know that sooner or later they will want to get Cable into the mix, whether that is in X-Force, or if he's introduced first in another movie. Actually, having him introduced in the Apocalypse movie could actually work...
