It's very odd that instant replay can be used to overturn a home run call but nothing else. What is the common sense behind that? Why couldn't a manager have say one challenge a game, like they do in the NFL? Or why couldn't there be one umpire in a booth somewhere watching instant replay? If there were no controversial calls then the game would proceed as it always does (very slowly indeed). But if there was an obvious mistake he would have the power to fix it. Not necessarily every ball and strike, but a significant play within certain parameters. Something along those lines couldn't really hurt the game.
