I donβt think the every five chapters thing will happen, thatβs would be a bit too stretched timewise. A lot of the Strawhats big moments should happen within a few chapters of each other, I donβt think it can be stretched out for 45 chapters. Like Usopp and Nami, who are working as a set.
But overall idea is a good one, with every Strawhat getting one chapter to show off something big as their announcement to the world that the Strawhats have hit Great Pirate status.
Not sure about the reverse-Saobody order either, since Jinbei throws that right out, and again itβs a bit stretched trying to match them all up
