Highschool DxD - Return of Demon King Lelouch

What if when Lelouch died, Great Red and Ophis saw this as an opportunity to have a descendant of their own and they revived Lelouch. After he was reborn, he was trained under Ophis and Great Red and then reborn as a member of Gremory Clan and then he was trained under Shiva, everything is different.. or most.
