There must always be a Stark in Winterfell, or: Sansa goes home.

Somewhere far away, far from the home she once knew – the home she can no longer remember, or she can but she does not wish too – there is a girl who does not remember her name, nor anything of the life she came from. Until the night she dreams of wolves.

Val didn't save Jon Snow - that was his direwolf and the red woman - but she did steal him.

When Dorne became one of the Seven Kingdoms, they agreed to replace the Westeros Law of Inheritance with the Dornish Law, so that the same laws would be followed throughout the realm. Or, Five times there was no male primogeniture in Westeros, and this wasn't as helpful as you might expect.

The king is dead, but a cousin cannot inherit before a brother, or before a sister.

"You could always stay." "And what should I do at the Wall, Sam, style myself as the Night's Queen? Or Lady Commander of the Night's Watch?" "Well, we do let girls in nowadays."

When Tyrion neglects to impregnate Sansa with the heir to Winterfell, Tywin decides to take matters into his own hands. But Sansa is no longer a little Northern dove; she is a Lannister with nothing left to lose.

The common folk whisper about the Council of Kings and Queens that rules over Westeros. They whisper that they are the Seven reborn.

She has no care of the Iron Throne--yet, and then only who sits on it, leave her be. She is going to reclaim her home, the place she once despaired of, dreaming of the sun and songs of the south. She was a Stark of Winterfell, there had always been a Stark at Winterfell, tales Old Nan told if the Starks lost Winterfell for good, the winter would win. Her mother scoffed at the tales, Sansa had as well, but whispers are on the cold wind. Winter is Coming. She was going to see the Spring.

Lyanna Mormont keeps the ravens.

Jeyne Snow and her siblings as the world falls apart around them.

“-my mother was not Lyanna fucking Stark!” Jon exclaimed, before turning and kicking, vehemently at the sofa, enough to leave brown dustmarks on the purple cloth. He turned back to her, lifting a finger threateningly. “I don’t care what you say. But our father would never- never- sleep with his sister, in fact I don’t even know why I’m telling you this because guess what, Sansa? You should already know that!” [Sansa tries to tell Jon who his mother is. Jon thinks he’s an incest-baby. Which........ isn’t wrong.]

Lyanna Stark thwarts a kidnapping, and receives an interesting offer.

King's Landing swallows Dornish princesses and chokes on their bones.

If you want a happy ending, that depends, of course, on where you stop your story.
