No, sword and shields implies that it's one object, when of course it is two. To say "I have two sword and shields" makes it sound like the SnS is a singular object. This is not the same for coat of arms, as the coat is the object, and the arms is the idea it is symbolic of. It's not the same as having two physical objects.
