If a project is so obviously in bad shape, management should be aware, otherwise they are incompetent. Therefore there is nothing to be gained by telling them it's messed up. Typical business time-frames do not allow for an entire team to start over on a project. Going rouge and creating an alternative solution is an option if the developer feels strongly that there is someone in management who will appreciate a better alternative and only needs a working proof of the idea in order to embrace it, but lacking that confidence, it's probably a waste of time.
