I’m curious if it would be possible to substitute Starkiller base in TFA with the fleet of mini Death Star Destroyers in TROS. Perhaps it’s a fleet of Star Destroyers where on their own, they’re very powerful, but all together can destroy planets. Like they took the power of the Death Star and spread it out so it wouldn’t be as easy as destroying ONE weapon to take it down, but the enemy would have to destroy every single star destroyer.

Thus, its as dangerous as the Death Star, without simply being another Death Star, and they are more difficult to destroy, as they’re smaller and the first order has more on standby of one is destroyed.

This way the fleet can be a more constant threat throughout the trilogy. (Maybe Starkiller Base functions more as the hangar where the fleet is kept? Idk I’m just spitballing at this point.)

The destruction of the fleet in TROS can feel like more of an ultimate victory. It took all the reinforcements brought by Lando to finally bring them down.
