Sure. A lot of fanfiction writers are more interested in exploring non - sexual relationships in the 'Harry Potter x Centaur' context.

These types of stories are often more about the magical world - building and character interactions, rather than anything inappropriate.

One idea could be that a female Harry Potter discovers a time - travel spell and goes back in time to try and prevent Voldemort from ever becoming evil.
