Would spare Puckle-style chambers solve slow reloading?

Could interchangeable loaded chamber assemblies improve a large Puckle-style gun?

The reply considers them possible at a smaller scale but identifies weight and recoil as obstacles for very large guns.

The follow-up proposes swapping a spent rotating chamber assembly for a loaded one. The answer accepts it as theoretically possible. It considers the weight prohibitive at battleship calibre, while tentatively allowing more scope around 6 inches. Another participant raises recoil and the strain on the mechanism. The exchange leaves the design hypothetical and gives no tested rate of fire.
