The databook doesn't list the Tailed Beasts as necessery components of 6PSM.

They didn't get his 6 Paths power thats why Indra hated Ashura. In the end without the 10 Tails or chakra straight from Hagoromo no one was going to achieve the same power he had, so there is obviously something incomplete with the Indra+Ashura=Hagoromo equation.
