Definitely. Discovering another material besides pyrolytic graphite that exhibits strong enough diamagnetism to levitate wouldn't get your name in the history books like room-temperature superconductivity would, but it would already be a major career-making discovery, with at least enough commercial value to launch a niche company. It would be very strange to tarnish your reputation with fraudulent, easily-refuted claims of superconductivity if you've already achieved such a breakthrough.
