Hagoromo is the son of Kaguya and half otsutsuki. So to say: "SP senjutsu is not related to becoming jinchuriki of Juubi", is true only for Hagoromo and Hamura. Madara says: naruto has SP senjutsu, sasuke the rinnegan, I have both. Both naruto and sasuke received SP chakra, in Naruto enhanced his SM, Sasuke awake the rinnegan. SP chakra, is the fusion of the most powerful Yin (Indra) and Yang (Ashura) which together emulate Hagoromo chakra. To awaken the rinnegan Sasuke need Naruto chakra, as Madara need Hashirama. To maximize this power you can only become a Juubi jinchuriki, or meet Hagoromo. TSB are part of jinchuriki form, if Naruto wants them back, needs ask chakra to other beasts.
