Note that he only got children after becoming the Sage, that apparently only Hagoromo's children have the Transmigrant ability and that Hagoromo appeared in his Sage of Six Paths form to Naruto/Sasuke. So, the Rinnegan that is awakened by Madara is the Rinnegan of the Sage of Six Paths, the one that has bound the Gedo Statue to it by summoning contract. It's possible that Sasuke's rinnegan only has the Six Paths Yin powers. (Considering Sasuke could easily learn the full powers of the Rinnegan from Naruto, who saw all them in use, and that he could use Asura path to restore his arm, it's a vague hint that Sasuke may only possess Six Paths Yin power and not all Six Paths).
 * As far as we know, Hamura becoming the Ten-Tails' jinchūriki was never even a possibility. For whatever reason the Rinnegan has a special connection with the Ten-Tails, since it's required to summon its body and perform the Six Paths Ten-Tails Coffin Seal.

Considering the running theme, it's likely he did not and was in fact born with a Sharingan. However, he clearly had the Rinnegan before Hamura had the Tenseigan, which is why he probably became Jinchuriki. Note that the Sharingan is essentially a Yin dojutsu while Byakugan is essentially a Yang Dojutsu. However, Hagoromo and Hamura have Yang respectively Yin Six Paths power. So the Rinnegan is a Yang-enhanced Yin eye and the Tenseigan is a Yin-enhanced Yang eye. Both are Yin-Yang eyes, just of a different kind.

Judging from the parallel between Naruto and Sasuke, and Hagoromo and Hamura during the Kaguya fight, i think it's clear that they initially were of roughly equal power, possessing each half of the Six Paths powers. Since Kaguya is part of the Juubi, being the Juubi Jinchuriki gives you (theoretically) access to her power which is probably how Hagoromo obtained the Yin half of the Six Paths powers.

Note that so far, Sasuke has only displayed the Six Paths powers of the Rinnegan that we can describe as Yin powers. Not saying it's a certainty: this thread was intended as a theoretical exercise and to see what people would expect of a Hamura Juubi Jinchuriki.

Additional question: Is it possible that, by being Juubi Jinchuriki, Hamura may switch his Byakugan for a Rinnegan? Especially considering the power of All Creation?
