One idea could be a crossover where Ichigo, with his Soul Reaper powers, is somehow transported to the Harry Potter universe. He meets some of the Arrancar there who have also found their way into this new world. They could be causing chaos, and Ichigo teams up with Harry Potter and his friends to stop them. Maybe the Arrancar are attracted to the magic in the Harry Potter world and want to harness it for their own power.
Another possibility is a story where the magic in the Harry Potter universe has a connection to the spiritual energy in the Bleach universe (where Arrancar and Ichigo are from). A powerful spell goes wrong and starts to merge the two worlds. Ichigo has to adapt to the new magical rules while dealing with the Arrancar who are also trying to take advantage of the situation. Harry Potter, on the other hand, is intrigued by Ichigo's abilities and they work together to fix the spell.
