thats a terrible idea! Mulan had hardly any musical numbers in it and the ones that were in, well they were hardly show stopping.
I think the future of disney in broadway does not lie in remaking their features into broadway shows anymore, I think they'll go more with fresh idea's or maybe taking their orginal idea's and twisting them into new storys and new worlds like they did with "Twice charmed" on DCL.
I could maybe see Pocahontas working but that would still be quite a push.
