Just a wild thought. What if Komurasaki is pretending to be Hiyori?

It was probably Kyoshiro Who informed Kaido and Orochi about the Alliances plans, I assume since he was holding the paper with the hidden message after he "killed" Komurasaki. So he told Orochi and then gave Komurasaki instructions to go find someone from the Alliance (just happened to be Zoro) and send Kamazo to ad for the effect. So when Komurasaki, Who pretends to be Hiyori gets to where Momonosuke is, they strike and takes down the Alliance
