Even if you could (which I'm not sure of, granted), doing so is counterintuitive. --- Go to Gamestop, buy a Steam card, and use it to purchase Ys Origin. You won't be disappointed. For more info: http://www.worldofys.com/yso/

On the boss rush front, apparently you can control your party setup in a way. I've heard that you access the mode in-game and your current party (with equips and set Skills) is used so you can fight all the bosses with just Adol if you access boss rush right when the game begins.
