As sonicbum explains, by the time CM2 realises ROLLOUT has not engaged, CM1 would most probably have applied reverse thrust. So do not even think about a go around.
In the case CM1 has not applied reverse yet, I would not think of going around neither. If you are not capable of braking the aircraft following the yaw bar, it will be much more difficult to accelerate again the aircraft along the runway at high speed.
