I think it comes back to the source.. does the person have the right implanted dna to regenerate the right chakra?? Madara had tiny Hashi flesh implanted into his chest/heart from what he bit off of Hashi's arm, so over time it mixed with him and he awakened Rinnegan. Sasuke had Hashi dna pumped into his chest/heart to forcefully repair it.. so he would have awakened Rinnegan eventually anyway.. borrowing half of Hag's chakra just shortened the process. So in reality Naruto would never be able to awaken the Rinnegan since he does not have an implant of Madara or Sasuke's flesh. Obito himself should have awakened the Rinnegan on his own once he implanted Madara's eye because eyeballs carry DNA and chakra too.. it just would have taken a long while for Obito's Rinnegan to manifest. One commmon trait between Sasuke and Madara is that it was their hearts that the Hashi DNA was implanted into in order to forcefully heal them all the way.
