I've always wanted to do something with magical kids learning their spellcraft in a Gothic Hoggwarts, a sort of Harry Potter-but-Dumbledore-is-actually-Satan thing.
What better setting to do that in than the mythical Scholomance?
Here's the set-up I cobbled together while drinking my morning tea & brimstone:
Books: Neil Gaiman, The Graveyard Book and Coraline; Edward Gorey, everything; Kim Newman, The Secrets of Drearcliff Grange School; Ransom Riggs, Miss Peregrine's Home for Peculiar Children; Lemony Snicket, A Series of Unfortunate Events series
Films: Dario Argento, Suspiria; Robert Eggers, The Witch; Andrew Fleming, The Craft
Comics: The Books of Magic, Ragemoor
