One possible plotline could be that the White Walkers invade the Naruto world. Naruto and his friends have to figure out how to fight them, maybe using their chakra in new and creative ways.
One interesting aspect could be the unique character of Harry within the context of the White Walkers. Maybe he has some special abilities or a different perspective compared to the typical White Walkers we see in the original series.
One reason could be time constraints. As the show went on, they had a lot of plotlines to tie up and not enough time to fully explore the White Walker story. So they just rushed through it.
It could be really strange. Maybe Harry Potter, instead of being a wizard, is a White Walker. He might have the ability to raise the dead in the wizarding world, which would cause chaos. His friends would be horrified and they would have to find a way to stop him or bring him back to his normal self.

The statement 'Game of Thrones punted white walker story' means that the show failed to do justice to the White Walker narrative. In the early seasons, the White Walkers were presented as this huge, impending doom. But in the end, their defeat was too quick and easy.

There were so many questions left unanswered about the White Walkers' origin, their ultimate goal, and how they were related to the overall lore of the 'Game of Thrones' universe.
In some fanfictions, a female White Walker could be the key to finding a peaceful solution between the living and the dead. Maybe she has some sort of ancient knowledge or power that could stop the endless cycle of violence. She teams up with some of the main characters from Game of Thrones, like Jon Snow or Daenerys Targaryen, and together they try to find a way to co - exist.
Since we don't have much to go on, Tez Walker could be anyone. He might be an ordinary person who had an extraordinary experience that is worth telling in the 'tez walker story'.

Sansa Stark could be an interesting pairing. It could be a story of two strong - willed women from opposing sides. They could either become bitter enemies or, in a more creative take, find common ground and form an unexpected alliance. Also, Margaery Tyrell is a great character to pair with Cersei. Their power struggle in the show was fascinating, and fanfiction could take it in new directions, like Margaery actually befriending Cersei and showing her a different way to rule.
