Can't Kakashi take Obito's Sharingan, and Sasuke take Madara's Rinnegan?


How come Kakashi doesn’t take Obito's eyes since Obito dies toward the end of
the war? Also, later in _Boruto_ , Sasuke loses his left eye. Is it possible
he can take Madara's Rinnegan since he was fully revived? Sasuke should be
able to locate Madara's body assuming the Leaf buried all of the dead shinobi
after the war.




Obito died by [disintegration](https://naruto.fandom.com/wiki/All-
Killing_Ash_Bones), so there’s no chance for Kakashi to obtain his Sharingan.
In fact, it was quite a big deal for Obito’s soul to briefly inhabit Kakashi’s
body and give him both his Sharingan in order to assist in defeating Kaguya.

I think it’s also safe to assume that Madara’s Rinnegan are no longer viable
considering the amount of time he’s been dead (even if it is true that
Madara’s body exists somewhere and is accessible by Sasuke).

But that aside, neither Kakashi nor Sasuke have shown any inclination since
the War to actively seek out powerful jutsu, whether ocular or otherwise.
