Or do you mean the term used by American Jews, yarmulka? It comes from the Polish word jarmulka, meaning cap. You'll be surprised to learn that most Jews don't use this term. Try kippa (singular) kippot (plural) for simplicity and universality. It also means 'dome' which is rather picturesque isn't it. With your kapo analogy you could even make a play on words to rescue your idea from banality.
