Maybe you could make a story spn Lucifer x OC, where OC is Winchester's little sister( maybe 20) from the same mother (in night where Mary die in spn she didn't go to Sam's room, demon kills her few years later, but one of boy's save their sister before he gave her his blood) Chuck decides to give archngels AND Sam and Dean a lesson, turn archangels into kids and making boy's their Nanny's in the bunker. Their remember all and hate boy's , making them so many troubles how they can. Winchester's have a prank war , everybody vs everybody and OC works with angels to kick her brothers butt's, Lucifer slowly falls for her with a puppy love and still love her when he is adult again. ( I look Jessie when I think about it, I just love Disney Channel shows, no matter I'm 18, lol) p.s. I love your stories , you doing amazing work
P.p.s. sorry for my English, it's not my first language
