One idea could be to rewrite the story from the perspective of a minor character like Neville Longbottom. Show his growth and how he might have influenced the events in different ways. For example, Neville could have been more proactive in some of the battles, using his knowledge of Herbology to create unique defenses against the Dark Arts.
Another interesting rewrite could be to change the time period. Set the story in modern day with all the new technology available. Wizards could use smartphones with magically enhanced features, and Hogwarts could have updated security systems using both magic and Muggle technology. This would bring a whole new dynamic to the story.
You could also rewrite the story to focus more on the relationships between the houses. For instance, create more interactions and friendships between Gryffindors and Slytherins. Maybe have a Slytherin character who secretly admires Harry and helps him out in some difficult situations, challenging the traditional divide between the two houses.
