One possible plotline could be that Harry discovers ballet as a form of self - expression. He might be struggling with the pressures of his normal life (like in the original story he has magical problems to deal with) and ballet becomes his escape. He starts taking lessons secretly and gradually improves, all while trying to keep it from his friends who might not understand at first.
Perhaps Harry is forced to study ballet as part of a magical curriculum. It could be that there's a magical ballet that has some significance in the wizarding world. He initially resists, thinking it's silly or beneath him, but as he delves deeper, he realizes the beauty and power within ballet. He then becomes really good at it and uses his newfound skill to solve some sort of wizarding mystery related to the magical ballet.
