If you continue to not find what you need and are willing to be a subject matter expert on what Pivotal actually is (because I never saw it), I would be interested in building this. A lot of people share your sentiment so it could be successful, but it's hard to clone something unless you know the thing.
Please not yet another failed clone attempt. If you never used it, you have absolutely zero chance of replicating it, its something you need to have experienced.
