When you think about it, a lot of Refs go to the line's men to ask what happened in certain situations and then make a decision either way from there. So why not have an official watch the game on a TV/Tablet in a room or whatever and when something does happen he can review it through replay and then the ref and ear-piece him and ask him what happened then the 4th or 5th official can tell him if it was, say, handball so really it's no different to when ref's get assistance from the lines man! Then the game wouldn't be held up as much.
