Anything they do will get unwanted change anyways. People won't want a fixed script that takes out stuff like "This guy are sick.", some won't want HD graphics, some won't want voice acting. There's no way to remake the game without upsetting somebody with a change anyways! I'm not saying it needs to copy XIII's system, but it would be weird if they just stand like they usually do while having HD graphics for some reason.
