One idea could be a crossover where Naruto somehow ends up in the world of Sansa. He could use his ninja skills to protect her from the various threats in her world.

Maybe he teaches her some self - defense techniques from his ninja training.
One idea could be a crossover where Naruto's world of ninjas and Sansa's world of Westeros collide. Maybe Naruto is sent to Westeros by some strange jutsu gone wrong and he meets Sansa. He could teach her some ninja skills to help her in the power struggles of the Seven Kingdoms.
Obviously Naruto and Sansa are the main ones. But for the Naruto side, Sasuke could be great. He has his own dark past and complex personality. In the Sansa side, Arya could be included.

One idea could be that Naruto is sent on a mission to a parallel world that is similar to Westeros. There, he meets Sansa Stark.

One great Naruto and Sansa fanfiction is 'A Meeting of Worlds'. It imagines a scenario where Naruto somehow ends up in the world of Game of Thrones and meets Sansa.
