It doesn't matter if you have Senju and/or Uzumaki blood along with Uchiha, you need Asura and Indra's chakra. never confirmed. It's implied, sure. But the only pool of Rinnegan we have is literally 2 people and the Sage. Not exactly a statistically significant population. The Sage of Six Paths confirmed it. He literally said the reason Madara gained the Rinnegan was because by mixing Hashirama's DNA it also merged his chakra with Madara's (both of whom were the reincarnations of Asura and Indra respectfully) which awoke the Sage's own chakra thereby awakening the Rinnegan.
