Fisrtly, Hamura has never been said to have any part of Juubi within him, neither by Hagoromo nor by anyone else. And secondly, Juubi cannot be reborn without Gedo Mazo being used as one of the components of its revival, while the Statue itself is currently sealed in Kaguya's core dimention, and there's no way to get it out from there (except, maybe, Sasuke summoning it with Rinnegan, but there's no reason for him to do so).
