Focus on the after Breaking Bad rather than the before
I wish they managed to show something happening before that doesn't reach a conclusion untill after, and then they focus on that.
Like: Saul has some bad deal with a criminal thanks to chuck. Maybe Kim has to sacrifice herself for Saul. Maybe Mike temporarily saves his ass. Cut to after BB: Mike is not there anymore and this criminal tracks down Saul.
So we see Saul finishing this off, take revenge on Kim, and maybe because of this he's able to relaunch his carrer/life (not that working in a cinnabon is not a carrer/life...)
I say this because it would lead into NEW territory that we don't know, rather than just expose what happens before BB all the time (we know who survives and who disappears, etc).
