Hamura didn't need the Juubi for 6 Paths Senjutsu, so the potential is there.

Indra believed power was most important. Regardless of who he was before Zetsu's intervention, it is what he wanted by the time the successor of ninshu was chosen. The thing that made Hagoromo the leader of Ninshu was the ability to spread chakra to people. He would need to pass this power onto his successor, so they would need to come into contact with his chakra. If it was a learnable ability, Indra would have been able to copy it and start Ninshu2 somewhere else.

Again, Hagoromo mentions giving all his power to Ashura. Who got 6PSen and no Rinnegan.
