That’s the only way I can see the show ending. They can’t let him get away with it

Sure they can...it's Breaking Bad.

He will die like a cat....off somewhere on his own. Legally he'll have "gotten away with it", but spiritually and at the cost of his soul and everything he held dear...he will not.

my original twist, before the first season 5 episode with him and the machine gun scene,

I thought Walt would wind up isolated and alone somewhere, making meth in small quantities from capsules again, and selling it himself, only to die in an alley, killed by a junkie he just sold to.

but that’s not how it will end now.
