One possible plot could be that Haku somehow survives and through a series of strange events, ends up taking care of Naruto as his mother. Maybe she uses her skills to protect Naruto from early threats in the village.
Perhaps in the fanfiction, Haku has some sort of time - travel or alternate reality experience that makes her Naruto's mom. She could then use her knowledge of the future or different world to raise Naruto in a way that changes his destiny, for example, training him earlier or teaching him different values.
A possible plot could involve Haku being brought back to life by some powerful ninja magic. And she discovers Naruto is in need of a mother figure. So she steps in, using her gentle nature and unique abilities. She might teach Naruto about his heritage in a different way than in the original story, and also help him form different relationships within the village, all while facing the challenges of being an unexpected mother figure in Naruto's life.
