For romance: NO Black Widow, Jean Grey, Mary Jane, Gwen Stacy, Ms. Marvel, Kitty Pryde or Emma Frost. They've all been done before, some of them way to many times oh and ABSOLUTELY NO FELICIA, Name someone you'd like him to be with.
Idea 2: MC died but was reincarnated in the world of Game of Thrones / Song of Fire and Ice as Gregor Clegane with The Hercules Method, I Want To Be A Hero Perk, and Beast Beyond Nature Perk as his three Boons/Wishes.
