Well, Quantum Corps does kind of roll off the tongue, so it might stick for that reason alone!
That being said, I would NOT allow the Quantum Bands to be duplicative of the Nova Helmets.
I would NOT have more than one race of beings be allowed into a Quantum Corps at a time. In other words, unlike the GLC or Nova Corps, if the Stygians (the original race to use them according to Quasar lore), have access to the bands, those bands can be duplicated many times, but ONLY FOR USE BY OTHER STYGIANS. If a Kree has them, then only other Kree can have duplicates and be part of the Quantum Corps. That might get confusing with a Phyla, for example, who came from a Kree/Eternal mix, and the Eternals have humans as ancestors, so I guess as long as part of an individual's genetic code was the same as the "main" host they could own and use the Bands as part of a Quantum Corps. Under that idea, Wendell (the main host), Avril, Phyla, and heck Peter Parker, could all be members of the Quantum Corps. I still would want each individual to have their own Superhero name - keep Wendell Quasar and have other Quantum Band users acquire other names - perhaps all names Monica Rambeau once had! LOL! (Pulsar, Photon, currently Spectrum, etc.).
As I've said before, I really want a story in which Wendell and Bob Greyson ("Marvel Boy/ the Uranian") finally meet. It's like a story 50 years in the making and I'm sad it hasn't happened yet. Maybe it can finally happen in the new Agents of Atlas comic? Maybe a crossover with Guardians of the Galaxy? Come on folks! Make it happen! Bob could even be part of the Quantum Corps himself!
