That will never fly as a “middle ground” because the second amendment was never written as a hunter’s law. It’s a Revolutionary, shooting-at-people law that didn’t take into account advances in technology because theydidn’tmatter.
What they had different were people upset with a government across the ocean and soldiers in their homes, and the only people upset with the colonists were slaves that weren’t allowed guns, education, or freedom. So that made the problem we face way less likely.
Any middle ground like you suggest would take a constitutional amendment and mass adoption, and the ones with the guns that aren’t likely to shoot up the place (Jan 6th excluded) are not keen on either.
