Margy and Sansa for queens on the Iron Throne
Okay, but they have to let Daenerys join and rule as a triumvirate when she gets to Westeros.
Daenerys burns all their enemies and drives off the white walkers and Margery is a cunning politician that solves hunger in Westeros and Sansa holds lovely dinner parties and makes friends with all these useful people by being a charming young lady
and together they rule the Seven Kingdoms with an iron fist
(and Sansa and Marg ride Rhaegal and Viserion respectively alongside Dany on Drogon)
Hey man, the dragon DOES have three heads.
