Should soccer use a 5-referee system with two on-field umpires?

With soccer looking more like WWF wrestling every day with the dives and such, why can't there simply be enough eyes in the proper positions to track the game and make correct calls? Every game there are a number of missed calls because the man in the middle simply cannot keep up with the play. It is just like watching a televised wrestling match where crap goes on while a ref is distracted. Sure the linesmen can raise their flages (which they seldom do) but they can't whistle a play dead and if the referee dosen't acknowledge the call they might as well be flagging down a train.
