In some of these stories, the character in the wheelchair might have to overcome the limitations of a Hogwarts that isn't fully accessible at first. They could use magic in creative ways to make the school more accessible for themselves and others with disabilities. For instance, they could create ramps or levitating devices with spells.

Harry would grow up with his mother's love and protection, and Lily would have to deal with the knowledge that Voldemort could return at any time.
I'm not really in favor of the 'slaves' concept in fanfic as it can be a bit disturbing and against the positive spirit of the original 'Harry Potter' series. However, some fanfics might explore power dynamics in a more metaphorical way. But overall, the official 'Harry Potter' works focus on friendship, courage and magic, not slavery themes.
