I would love to do a Lufia: The Legend Returns climax in Lufia II graphics as well. The only issue is... there are like 4394832904 characters in that game and making sprites for each one would take quite awhile, especially for something that is just used for promotion and not actual in-game content. As for collaborating... as much as I'd like to, its so more stressful to get everyone to work together and get all the assets to everyone and etc etc.
