The only necessary modifications to season 4 would be the inclusion of the Hero-faction grunts and Ise trying to communicate with the past possessors. Otherwise season 4's content itself does not need to be changed by TNK.

As an LN reader who disliked BorN for the most part, I do hope for a 4th season as they promised they'd stick to the original story and they know fans in Japan won't stand for screwing up v9-10.
