Raven-Symone to Raise Her Voice?

Could lil Raven-Symone be heading to the Great White Way? That's the report coming from deadline.com. Raven-Symone, most recently known for her work on her Disney Channel sitcom "That's So Raven", is said to be taking over for Patina Miller in Sister Act at the end of March. So, will this stunt casting work or will she be the Oliver Factor (google it if you don't know the reference) of Sister Act?
