Aro's Half-human Child

It's been a few years after Breaking Dawn and Aro decides to create a hybrid of his own. He had killed Joham and his two oldest daughters Serena and Maysun. But allowed Jennifer to live and go stay with her half brother Nahuel & his aunt Huilen. The Cullens now live in Alaska and have never been bothered by the Volturi again since the hybrid incident. Any Aro wants a hybrid child for himself and his mate Sulpicia, who has always wanted a child of her own. Sure they had raised Jane and Alec for a few years before they were old enough to turn. But it's not the same as having your own child. Only problem female vampires can't procreate.
