Synchronizing 100% character models does not sound easy. The dilemma is that the older outfits and layer wear are modeled to fit the older pso2 body. In order to synchronize it, they would have to recreate from scratch (haha pun) 8 decades of cosmetics. That is unlikely to happen. Well, I mean that I would be ready to shed a certain percentage of these makeup to keep things intact across versions. Provided that there's a continuous feed of cool new things to replace it, I do not mind. I constantly rotate out my old looks anyway. So long as the character versions translate 1:1 it will still feel just like mine.
The example I can think of is the Dragon Hunter Frontier Z collaboration where I can envision the clothing and weapons could definitely be provided a visual update together with everything else but that I don't exactly understand how the licensing or the way the lawful side of this cooperation functions where I'd wish it had been as simple as Sega going through and updating the resources but I don't know about just how much Capcom is involved in that process.
The same applies to collaborations such as the Final Fantasy XIV collaboration with Odin (which exists as far as I know) where I don't understand how much Square Enix is involved that for Sega to have the ability to upgrade assets there. When it was only just Phantasy Star-related things (like character outfits, cameos from other games, or other Sega-related properties) I could imagine that this likely would have been achieved, or would be carried out. But in the Global version we don't have the existence of Cougar NX therefore I do not exactly know if there are additional complications regarding Sega's properties that may also contribute not to updating everything they can within reason.
