I think its very likely there will be something along these lines but perhaps not the story elements of deciding the fate of the fort (but with the NPC and modding infrastructure couldn't it possibly be a modded story?) they recently talked about they had huge plans for the military and map expansion to fort knox. Also they talked about how if they needed a certain location or building for story purposes they would build it, so eventually fort knox could be a part of the kate and baldspot story when they build it
