There are three wonderful Disney musicals from the 1960's which would transfer beautifully to Broadway. One of them, Babes in Toyland, WAS a big hit in the early part of the 20th Century and features a fantastic Victor Herbert score with new lyrics by George Bruns.
Also Summer Magic and The One and Only Original Family Band feature songs by the fabulous Sherman Brothers and would be great as stage musicals.
Best of all, come to think of it, would be 1967's The Jungle Book, also by the Sherman Bros. Jungle Book would probably be the most likely to succeed since it has a similar setting but a score and story that is eons better than The Lion King.
