So pretty much everyone who's played KH3 and ESPECIALLY the dlc agree that Yozora looks like Noctis 2.0, which is why I think it'd be fitting if we could get his outfit or even just swap his model for Noctis'. It wouldn't even be that hard to get his equipment to work.

His sword isn't that different from the Ragnarok in terms of appearance, and his crossbow functions more like a pistol anyway. His outfit isn't really that different than Noctis' default one, you could probably get away with rigging it the exact same way.
