Same for Itachi if he had indeed taken Sasuke's eyes and then got a hold of Asura's chakra by means of Hashirama's cells or Naruto's etc. With the information we have, the answer would be yes. But just his eyes would transform, he would thus be more akin to Nagato than Madara himself.

Maybe, Madara's/Sasuke's (and thus Indra's) chakra would stay in these eyes anyway, but it wouldn't be a large quantity of it, and after recalling how long it took even for Madara, the true inheritor of Indra's chakra, to get the mix of his and Hashi's (i.e. Asura's) chakra to awaken the Rinnegan, I somewhat doubt that Izuna or Itachi could really achieve the Rinnegan during their natural lifespan, even if it would've been longer for them than in the present storyline. I think it took this long because madara had very little of Hashirama's cells. He had only bitten off a tiny piece and used it on his wounds.

So either Itachi should be gifted that rinnegan or something I guess.. Sasuke possesses the natural ability to awaken the Rinnegan, since he met the conditions. But as can be seen with madara, it takes a while. The Sage simply made that process faster while also ensuring his Mangekyou could be used alongside it. That he only has one is also likely the Sage's doing, since it would prevent him from taking Madara's place.

Obito's own body is Uchiha, so it's accustomed to having dojutsu. It's the body part that needs to be of a similar clan in order to properly use the rinnegan.

Lorenzo.r.1st wrote: and secondly, dna is dna. that's the thing... it almost never changes. Specific forms of chakra seem to take a role similar to DNA and if that chakra changes, apparently so does the DNA. The reverse is also true: Changes in DNA result in changes in chakra (See: Kabuto). Else, the Rinnegan awakening would never work.

Namikazenaruto9 wrote: come on even if acceleration took place why single rinnegan? why not dual? And besides if sasuke really had hashi's cells he hasn't shown wood release. So this is moot point. He was probably injected with Zetsu cells, which show no meaningful control over wood release. Obito controlled wood release when supercharged by Spiral zetsu, and we already saw that that zetu can also increase Yamato's power. The single Rinnegan is so he can't take Madara's place, since you probably need dual rinnegan to get Rinne Sharingan. Since Hagoromo would be stupid not to realize Sasuke would fight afterwards, he probably also consciously limited his power.

it's not exactly clear what Kabuto's final intent was with Sasuke (other than to make him awaken the rinnegan, since that was clearly the plan). But we've seen that Zetsu material is much better for healing (non-hashirama) stuff than Hashirama's primary cells because those cells aren't aggressive (IE Danzo nearly died when Hashi's cells were unrestrained, yet Obito could control half a zetsu body as a kid. He also can't freely use wood release. Neither can Naruto or Sasuke, suggesting those arms and injections are Zetsu injections/arms)
