I would prohibit all spear guns or other "shooting" type of weapons, but a Hawaiian sling or a tipped spear is about as safe as you can get, and everything you need. The lionfish darn near wait for you to kill them, it's not as if they're difficult to hit. It would be fairly easy for a DM to determine after the first dive whether or not you're qualified to carry a spear or a sling.
There is money to be made here, I would pay to rent a collapsible sling from my op, and I would pay a few bucks a day to get a "license" from the park to hunt lionfish. If they can use my few bucks to fund a larger scale response to the invasion, all the better.
I've dived Cozumel enough to have seen the majority of what is there to see, I'm looking for something more to do when I dive. Hunting lionfish while helping the reef survive would be something that would bring me back to Coz many more times.
