Yes it is. Let me answer your question with a question. Why did Kabuto want to join Obito? For Sasuke right? Well Sasuke was right there in front of him yet Kabuto was fighting to keep Edo Tensei up. All he had to do was recoffin the Edo's still free such as Madara, Chiyo, and Kimimaru then end Efo Tensei and Itachi would be gone neg diff. Kabuto would solo Sasuke with white noise and using his medical ninjutsu to render Sasuke unconscious ( he done so to Kiba with his medical ninjutsu). Oh and he would have been able to coffin the Edo Jinchuuriki giving him the Bijuus since they were his Edo's and he allowed Obito to use them.
So Kabuto would have ended the war early on and go into hiding as he conducts whatever experiment he wants to with Sasuke and the Sharingan. We probably would get Kabuto in Sasuke's body with all of the abilities Kabuto had from Karin, Suigetsui, Orochimaru, and the sound 5. Probably will be a time skip where he conducts those experiments and learn to use Sasuke's body and power.
Also how is Izanami going to be able to be used without Senju DNA when it's pair requires Senju DNA? Having both DNA is what gives Izanagi it's power yet plot deems one of the pair to be on the same level but not require the same requirement? Another plot hole was that Sasuke and Itachi could move their heads to look at each other and even talk when they were under the sound genjutsu that paralyzes the body. Shikamaru couldn't talk or move an inch, he had to make his shadow break his finger to break out. Kabuto is powering up that sound genjutsu with Senjutsu which means it's much stronger than what Tayuya used.
