<p>If I have to make something up, then sure. Itachi will end up sealing Kimi and Konan early on, he's not stupid and knows they are Edo Tensei. Then its down to Itachi vs Oro, Oro would try to poison Itachi with a snake bite, and avoid his eyes which did not work last time, but he will try anyway. Oro spits out his sword, and slashes Itachi only to find its a bomb clone, and he gets injured, he heals himself at the cost of chakra by shedding his skin, he shoots a snake arm at Itachi, it turns out to be a crow clone and the real Itachi was in the distance behind it, he lands eye contact with Oro putting him in the shackling stakes genjutsu, Oro is stronger now, so he breaks the genjutsu in a shorter time than before just barely managing to keep his head from getting lopped off. Itachi hasn't used MS yet. Oro uses Slithering Snake mode for the maneoverablity and goes in for a physical confrontation, they clash for a few mins and Itachi being so fast evades the last strikes and jumps away only to land near an explosive tag Oro somehow set.. turns out it was another crow clone and Itachi appears and shoots Great Fireball Jutsu at Oro who summons the Rashomon gates at the last second. Realizing it will go back and forth, they each think they need to end the battle before too long, with Itachi thinking of his smaller reserves compared to Oro. Oro uses the Yamato No Jutsu, Itachi goes into Susanoo, with YM and SoT ready. Same clash as before, the difference being Oro is watching for the SoT this time, and Itachi since he is in prime has much longer to use Susanoo and his techs than last time. Oro has the Yamato heads lunge at Itachi, while the head he is on attacks with the Kusanagi, Itachi blocks all attacks from the front with YM Oro uses that disctraction to go into Hiding like Mole tech to dig under Susanoo to get closer to Itachi. He springs up to slash Itachi, but Itachi is not there.. He is outside his Susanoo which he deactivates instantly, with Amaterasu now upon Orochimaru. Orochimaru sheds his skin as fast as he can and goes underground again, lunging at Itachi again with his Kusanagi and Shadow Snake Hands, Itachi is hit but disperses into crow clones which Oro uses his many shadow snake hands to hit all at once, Itachi uses fireball no jutsu again and Oro goes underground again to avoid it. Oro comes up and uses great breakthough as fast as he can and as soon as it activates he shunshins over to Itachi, bites him and then and stabs him. Itachi makes Eye Contact with his Mangekyo activated, using Tsukuyomi. Oro has no way out and Itachi takes mortal damage, Itachi ends it by sealing Orochimaru again, or cutting off his head and burning him to ashes with Amaterasu. The stab wound and the poison eventually take effect and Itachi dies, Itachi knew Oro would kill him in a long drawn out battle due to his smaller reserves, so he elected to take Oro out even if it meant he dies afterwards. If this was the old Oro from before taking over the White Zetsu and some of Kabuto's flesh, then Itachi could have won without dying.. but this Oro should be stronger than the old Oro.
