It's a crazy possibility. But what if they're connected in some way that they share the same forbidden technique. The crazy theories usually always have a possibility. Just like the guy who predicted that naruto's clone would be sent into another dimension.

Also, to be honest. I can't see it be anyone we've mentioned. Izuna, Shisui, Kagami, s06p, obito. Something with all of them just doesn't click. Oh well.
