My guess on how this all ends is that Hank mills over this idea for a bit because he can't believe it's possible. Eventually he confronts Hank, who maybe tries to play it off. Then tries to tell Hank that he's out and fake begs that he's just a nerd that got over his head and he just wants out. When it's clear he isn't getting what he wants he goes full Heisenberg starts naming off all the crazy shit he's done under Hanks watch, which includes probably offing Mike and Brock, maybe even Jesse's ex girlfriend. Hank doesn't know what to do, so he leans on Jesse and lets him know about Mike, Brock, and the girl. This'll set up Walt Vs. Jesse for the final run.
