What we know so far:

How Uzumaki/Senju descendant get rinnegan: Uchiha Chakra+Sharingan transplant(obviously from an Uchiha)=rinnegan

How Uchiha descendant get rinnegan: Uzumaki/Senju Chakra+their own sharingan=rinnegan

BUT, a person who isn't truly a Uzumaki/Senju or Uchiha descendant can't get rinnegan( well, they could, if they stole it from a descendant, but that's mean) even if they have Uzumaki/Senju or Uchiha chakra in them.

But then it begs the question why doesn't Naruto have rinnegan. He got SO6P chakra(which contains some Indra/Uchiha chakra) so all he needs is a sharingan transplant to get rinnegan,right?

And isn't there even a slight possibility that a rinnegan will manifest in Naruto's eyes at a given time?
