Thats what i mean, since Zoro is both a powerhouse and the guardian of the Strawhats, i can even see Zoro guarding Wano and fighting CPs and finally even Ryokugyu on his own (in order for Luffy and the other crews to be able to leave first), lifting the spirit of The Samurai so that they unofficially round up at Zoro's lead to fend off WG's army, thus Zoro getting the glory and recognition from Ryokugyu as Second Ryuma. Maybe after that Zoro can explore his own lineage and lore in solitary adventure at Wano etc before catching up to Luffy (by unknown means, maybe hitching a ride to a passing ship somewhere?). Somewhat fitting imo, but i'm also currently seeing Oda in a pessimistic light regarding plot coherence lol
