Well, the last person who was used as a vessel of sorts for Kaguya's resurrection was a juubi jinchuuriki with the rinnegan and even a rinnesharingan. Sarada is not even a transmigrant.
The last time she got sealed Madara had to absorb the chakra tree in order to revive her. Jigen mentioned there will be another chakra tree and he already has a juubi. The only juubi we know about is the one fused with Kaguya. In order for her to be revived she would need another vessel similar to the role Madara played. Since Kawaki and Boruto are already taken the next most likely candidate would be Sarada. This is all based on the assumption that the Otsutsuki depicted in the place Sasuke found are all going to be revived one way or another.
Im guessing that you dont think its a possibility. I think its the simplest way for to redeem the Uchiha clan and become Hokage.
I think that one way or the other it will happen karma seal or not. The Kaguya situation has to be addressed or the series is incomplete imo.
