The Remnants Of The Rocks Pirates Already Revealed?

Here is something very interesting:

From Chapter 957 (Wano)

From Chapter 452 (Thriller Bark)

As we know, after he died, Captain John’s corpse came into the possession of Dr. Hogback. With Hogback’s surgical skills and Moria’s Devil Fruit powers, the corpse of John was modified into a zombie.
Since John was one of Moria’s Zombies, could it be that also Silver Axe and Wang Zhi’s corpses were modified into zombies?

What do you guys think?
