guys, first of all im new here, and i think theorizing for anime is great ^_^
but i think youre all wrong as to what the six paths are. i think instead of actual people, we have to look at their individual qualities.
one path could be to actually have a sharingan, which madara already has,
another path could be senju blood, since izanagi is a rinnegan doujutsu which madara now has.
the third path could be nagatos rinnegan, obviously.
sage mode, could be another of the six paths
and the last two things i can think of are
to be able to become to juubis host, which could explain madaras moon eye plan
and lastly, the sages body and spirit.
another thing im thinking about is the gift itachi gave naruto, could it possibly be something to negate the effects of izanagi? just like itachi implanted an auto amaterasu in sasuke to activate when he sees madaras sharingan, naurtos mystery power could be an auto negation of inzanagi, then again, itachi hoped that naruto would never have to use it, which could mean its meant for sasuke, but it is some kind of lead
