The big issue with that proposition is that, well, there are characters, such as the Tailed Beasts, who already know all about the Juubi, Shinju, and Kaguya. However, Gyuuki doesn't mention the Shinju at all, a bit of info that would have saved many lives, until the Juubi had formed into the Tree. Madara and Obito mention the history of the Sage and the Juubi, but Kaguya never comes up until the Tree is formed. Madara had no intention of bringing back Kaguya, so he didn't need to hide that info and could have revealed it a lot earlier. And don't get me started on Hamura.
