What if Tywin gave Tyrion the Rock?

[3rasmus]

Let’s say in an alternate universe, Tywin has just enough respect for Tyrion to give him his seat at Casterly Rock. Tyrion negotiates that he’ll marry Sansa and consummate the marriage, in exchange for the lands of titles of the Westerlands. Tywin of course knows Tyrion will probably make it his “whorehouse” but he respects Tyrion’s intelligence and ability to rule enough to ignore it, and he’d be out of the hair of Joff, Cersei, Pycelle, and others who despise him and would probably support the idea. Olenna would still probably plot Joff’s murder, but without Tyrion and Sansa, who is to blame? How does Sansa’s arc change if doesn’t go north with Baelish? I’d assume Bronn goes with Tyrion to the Rock, which means no “diplomatic mission” in Dorne, and no Oberyn death with no Tyrion trial. How does the rest of the series play out?

Why would Tyrion leave King's Landing? Tywin is still alive, so Tyrion would be just the heir to the Rock. The seat has a castellan, and Tyrion's duties at  Master of Coin require him to be at court.

He’d leave to get out of Tywin, Cersei and even Joffs hair. Tywin knows Tyrion is the most politically inclined of his children (in this case he admires this quality). It isn’t too out of the ordinary considering he sent Tyrion to serve as hand “in his stead” and would send Jaime to rule in CR at any given opportunity. Tywin knows Tyrion can be useful to the house, and sending him to CR puts him out of risk from Joffrey. Tyrion was always playing devils advocate for the Starks anyway.
