And would it really be too late to roll out something like that?... Sure there have been quite a few submissions already, but I would hope no one has has put any real effort into the overworld of their rom so they wouldn't mind updating their submission for the sake of convenience (but I obviously can't be speak for everybody) and it could save a lot of time on the part of the judges.
But on the other hand, it could also be a huge hassle and not worth the effort.
