Is that Obito who is not an incarnate but was an Uchiha with Mangekyo and Hashi's dna/chakra never could awaken the Rinnegan himself.. but then again Madara himself said you need both your original eyes to awaken the Rinnegan didn't he? He didn't know you have to be a reincarnate to awaken them. You need both pieces of reincarnates to awaken rinnegan. If youre uchiha then you need a portion of the flesh of senju. If youre senju/uzamaki you need the other transmigrant's dojutsu.

Even having six paths chakra and having only one piece of sage will only allow u to reach the full potential of what you have. Naruto and sasuke are examples. Naruto only possessed the sage's body so even though having six paths chakra, he wasnt even able to awaken rinnegan cause he didn't possess a dojutsu. Same goes for sasuke not possessing the body. Madara is different cause he was actually able to steal a portion which is why i think he is different possessing body and eyes.
