A great fanfiction idea could be a crossover where the Scooby Gang from Buffy's world visits Hogwarts. They all have their own skills and personalities that would interact really interestingly with the students and teachers at Hogwarts. Xander could make friends with the Weasley twins, while Willow might study magic with Hermione. And Buffy, of course, would be the one ready to fight any danger that arises.
One interesting crossover could be Buffy teaching the students at Hogwarts some self - defense spells that are more combat - oriented than the ones they usually learn. For example, she might introduce ways to fight vampires and demons using magic in a more hands - on way.
One interesting aspect could be the exploration of Buffy's moral dilemma. In fanfiction, she might face situations where slaying another slayer is not as straightforward as it seems. It could be due to misinformation or being forced into a corner.
Another idea for a Buffy - Harry Potter fanfiction is a time - travel story. Buffy somehow travels back in time to the era of the Marauders in the Harry Potter universe. She could get involved in their adventures, and her presence might change some of the events that are later important in the main Harry Potter storyline. This could lead to all kinds of interesting twists and turns.
Harry Potter himself is often a popular character in these crossovers. His connection to magic and his hero status in his own world make him an interesting figure to pair with Buffy. He can bring his knowledge of spells and the wizarding world to the mix.

Well, there could be a story where a powerful dark magic object from the wizarding world is brought to Sunnydale. Buffy discovers it and realizes it has the power to disrupt the balance between good and evil in her world. She then travels to Hogwarts to seek help from Harry Potter. Along the way, she meets various magical creatures and has to navigate the wizarding world's politics. Once she meets Harry, they discover that there is a common enemy behind all this, someone who wants to use the chaos in both worlds for their own gain, and they must work together to stop this mastermind.
Well, perhaps there's a spell in the wizarding world that accidentally opens a portal to Sunnydale. Buffy stumbles through and finds herself in Hogwarts. The Hogwarts students are initially confused by her, but when they see her fighting skills against the dark arts, they start to work together. Harry could learn a lot from Buffy about facing the unknown fearlessly, and Buffy could gain knowledge about magic from the wizards.
One idea could be that Buffy and her friends are transported to the wizarding world. Buffy could use her slaying skills to fight dark creatures in Hogwarts like Dementors or werewolves. Maybe she teams up with Harry and they teach each other their unique fighting styles.
