Naora has long since gone freelancer, but he's still on very good terms with Kawazu and has worked on some of his recent projects even after going freelance, I'm sure that he'd be up to work on Unlimited again given the chance.
Unlimited's is also in a good spot when it comes to its 2D assets because they were made at a higher resolution than the PS2 native one, which is one of the reasons why they upscale to modern resolutions so well, they really shouldn't need to touch anything up outside of the 3D parts of the game.
