I think the real roadblock would be that there would need to be some sort of AI for the rest of your party (and for the enemies as well). As it is right now, you're easily able to control your entire party in combat because it is turn-based; only one character is controlled at a time.
If the turns are taken out, all of a sudden you're controlling just one character while 7+ enemies wail away at your party (assuming they can be changed to work in RT as well).
