Don't know about the chances, but I think that writers & producers definitely want it to happen. There have been multiple tryouts/productions with high-profile performers, with some regular Broadway non-profits co-producing. It might have a longer gestation period than fans want, but from what I understand - with every tryout, they've beefed up the material more and more. From snippets available online, and reviews from my trusted friends who've seen the shown, the material is quite strong.
