Is Chapter 925 the setup for Mihawk’s death?

There are two popular theories for the end of One Piece: every Straw Hat member fullfills his dream and there will be an epic battle between the Blackbeard Pirates and the Straw Hats.

Important for my theory is Zoro’s dream. He wants to be the strongest swordsman in the world, but many people pointed out that it would be kind of odd for Zoro to fight Mihawk for the title after they established a teacher-apprentice relationship.

Now to chapter 925. We got a confirmation that Perona and Mihawk have some kind of relationship and Perona wants to meet/reunite with Moriah. But Moriah is on Blackbeard’s island and will probably be killed or captured. Assuming Perona finds Moriah, she will be captured or at least in danger too.

What if Mihawk tries to rescue Perona and he fights against Shiliew? I’m sure Mihawk beats Shiliew in an honest fight, but with the new Devil Fruit of Shiliew, he would be able to play dirty tricks very easily.

Assuming Shiliew kills Mihawk, he would claim the title “Strongest Swordsman in the World”.
This would perfectly fit in the first two theories. In the epic battle against Blackbeard, Zoro would fight and defeat Shiliew and become the strongest swordsman in the world, fulfilling his dream.

Do you agree? What are your thoughts on it?
