I don't think that would work although I'm only speculating as well. I think the reason that external consultants can work better is that they exist in a different political situation than most internal managers do. A lot of basic management skills are human nature or basic survival techniques such as being efficient, and even untrained managers probably have those, but internal managers just don't have the political situation where they feel they can propose changes and keep their job secure.
