Rap is basically impossible to do well in Ultrastar, so I don't see this one working out. Sorry! :(
Well, they did make the ERBoE Iron Will vs. Zecora, but it is true that it doesn't really have a score to it. If it is made, it simply won't have any more than rap lines and therefore will follow the same style as ERBoE.
