One idea could be a crossover where Pietro uses his super speed to deliver important Hogwarts letters that the owls can't manage in time.

Maybe Pietro's sister Wanda also gets involved and her magic interacts in strange ways with the Hogwarts spells.
Perhaps there's a fanfiction where Pietro Maximoff is a descendant of a long - lost wizard family. He discovers his heritage when he meets Harry Potter.

One idea could be a crossover where Harry Potter's magical world collides with the mutant abilities of Wanda Maximoff and Jean Grey.

One idea could be a story where Clint Barton and Pietro Maximoff are forced to team up during a mission. They start off not getting along because of their different personalities and fighting styles. Clint is more of a traditional, precise marksman, while Pietro is impulsive and super - fast. But as the mission progresses, they begin to understand and respect each other, and by the end, they form a strong friendship.
One way it could happen is through magic. Harry Potter is well-versed in powerful magic. He could use spells like 'Episkey' or more complex healing magic to mend Pietro's injuries. Maybe he'd have to study some new spells specific to Pietro's unique speedster physiology.
Pietro's super speed could enhance Harry's ability to quickly move around Hogwarts during a battle or while searching for something. For instance, if Harry needs to reach the Room of Requirement in a hurry, Pietro can carry him there in an instant.

A plot could be about a student who has a phobia of large groups (agoraphobia). At Hogwarts, there are always big gatherings in the Great Hall, Quidditch matches, etc. This character could struggle to attend these events. Their friends could try to help them gradually face their fear, and in the process, they might discover a magical solution or just the power of friendship to overcome it.
One plot idea could be that Urahara Kisuke somehow ends up in the Harry Potter universe. He might use his unique inventions and skills from the Bleach world to help Harry and his friends in their fight against Voldemort. For example, his kido skills could be translated into new spells in the wizarding world.
A plot could be that the Death Star is actually powered by a piece of Voldemort's soul. Hermione discovers this through her research. She then teams up with Luke Skywalker to find a way to destroy the Death Star in a way that also destroys Voldemort's soul fragment. It would be a race against time as the Empire is planning to use the power of the Dark Lord's soul to conquer more planets.
