I don't want Zoro to die, but i want him to be crippled in this arc for interfering in Luffy vs Kaidou fight, a lesson for Zoro. Maybe after broken bones by Thunder Bagua (no Hakai involved), he will realize how difficult Luffy's path is (as the one responsible for surpassing Kaidou, responsible of becoming the strongest individual ever etc), completing his full belief in leaning/relying on Luffy regarding this matter.
...and try to find the meaning in his own path, the meaning of the sword philosophically, the delicate techniques from Koushirou he sidelined all this time for learning (brutal) haki and the deeper meaning behind the sword discipline, etc. So when he healed in the next arc (Elbaf?), he will be a much calmer (less brutality), philosophical, and technique-oriented person compared to before.
While Luffy should instead depart away from his crew temporarily, attending other matters (and finally being offscreened for the first time in the manga, after surpassing WSC), giving his crew the time to shine. Maybe make Hancock calling him for help or assistance since she's hunted by admirals or something? Maybe he's lost in his own adventure? A sidequest in finding some artifact in far corner of Elbaf? Tldr the renewed Zoro should be the temporary leader in the main Elbaf arc during Luffy's absence.

...and i also want Law to join as Strawhat core member, with Heart Pirates as a part of Luffy's Grand Fleet. Nothing to do with the thread but i just wanna slip that in
