Not really. Utilitarians who try to find utilitarianism in other ethical schools can certainly do it, but it only makes sense to them as utilitarians. Deontologists generally don’t accept their formulations because their first principles are different, and that’s actually the key thing that people care about in discussions about ethics: the values that motivate them.

For most situations, all ethical schools of thought wind up with the same answer (unless you’re an Ayn Rand devotee). Those aren’t the interesting parts of ethical theory though, the places where they disagree are the margins where the actual theoretical work is being done.
