Considering how Hagoromo emerged from Madara's lower half, and how the latter already had Indra's chakra, Asura's chakra from Hashirama's cells, absorbed all nine tailed beasts, but half of Kurama's original form, I think what Hagoromo meant by mixing "Indra, Asura and the Kyuubi's chakra" bringing him forth was that maybe enough of Kurama's chakra grew back or something... I mean yes it was only Yang Kurama, but it could still use the Tailed Beast Ball, which requires a ratio of Yin and Yang chakra, so maybe enough Yin chakra or something grew back, mixed with the rest of the nine tailed beasts, brought forth the Ten-Tails chakra, which mixed with Hagoromo's two sons' chakras, and brought forth Hagoromo himself. Sounds complicated, I know, but that's what I think.
