You're serious about that?
Zoro is implied to represent the moon, even one of the ancient moon people who seemed as higher ranking was depicted as Zoro based on the ear ornaments:
With Shimotsuki being translated as "frost moon", as the Kozuki's name bearing moon in it and Zoro saying he will become the new leader of the Samurai. Essentially being the successor of Ryuma, god of the blade and deity of Wano, who slayed down a Dragon above the capital.
And in mythology, sun and moon are equal or in relation.
It's clear as day. Zoro won't just sleep at the climax of an arc that revolves around such a powerful lore.
