As Sam Nielson alludes, The Hunchback of Notre Dame as written is not exactly fertile ground for growing Disney princesses (Esmeralda dies, Quasimodo kills Frollo, then starves to death at Esmeralda's graveside). (A strong second place for inappropriate cartoonification is Don Bluth's Anastasia.)
But if that worked... Perhaps the world is ready for Disney's Romeo and Juliet. Or Wuthering Heights. Or Frankenstein...
