Fan Casting Harry Potter reboot series

I have an idea for a Harry Potter reboot series. In this reboot I imagine the Dursleys abused Harry more than they originally did and lives with Sirius and his wife called Daisy. I know Sirius wasn't married but I wanted to have original characters. In this reboot Harry behaves in a way that might make people think he has autism and is a little more immature than the original Harry. I would also have him lose his parents around age 5 or something and is able to remember it. He also always knew he was a wizard. This is my fancast for that reboot series
