From what i have seen and read if you could drag a demon or whatever elite to any location there would be no problem with it , that is why the Boss in shattrath now has amazing health as all blizzard did was boost him after he was killed a few times , so i cannot see any problem with it as it has been done so many times .
I have seen the felreaver in hellfire kited and that's fun to watch , hehe better than him stomping on me anyway.
