If Bob and Bill part ways, most likely everyone on your list departs.
But this board will erupt when it's announced Bill returns as HC for the Pats for 2024. Unless he's traded, he may make more money getting paid the remainder of his contract then take another HC gig which would void his contract. He won't sit out until he's done being paid by Kraft. Because of this, he will want his sons employed so he will give up GM duties to remain in NE. Bob doesn't have to go through the Head Coaching search and Bill stays. Everyone wins.....
