Hazel Black (Potter) and Hogwarts for a bit.

Hazel Potter, older sister of the somewhat declared Boy Who Lived, she was adopted by some blacks (fan made characters) who moved to America.

Hazel now is in Ilvermorny and some students (all friends) get to go to Hogwarts for a bit.

When Dumbledore realises what he has done.

It is too late..
