you know how madara gave nagato his rinnegan and nagato most likely being from the uzumaki and maybe having some senju in him he brought out the full powers of rinnegan so should kakashi be able to use amatarasu and tsuyumi and susanoo even tho he isn't of the uchiha clan?
No those are specialized jutsu's for each
person. For example Itachi has his Tsukymo or
whatever. Tobi's mangyeko is Kamui, and
Kakashi is able to do that. Susanoo can't be
done because you'd need to have both eyes.
Tobi's power is basically cut in half because
he can only rely on one.
i dont think kakashi can take obito's eyes
even if he dies..... unlike rinnigan, sharingan
and byakugan needs to be activated.... however,
those who are not born withthe kekkai genkai
(blood line limit) , they cannot shut it down.. it
is constantly activated on their eyes and the
chakra drain is heavy.. thats why when people
without the kekkai genkai take up those eyes they
take only one....just like the mizukage's
bodyguard who has one byakugan..... if kakashi
takes both sharingan's he will have to keep
both of his eyes closed all the time unless he is
battling ... just like he now keeps the sharingan
eye closed ........... otherwise he will be
constantly out of chakra....
