The only reason they'd want to add a bigger sub potentially would be if they added multiplayer, and even then, the cyclops would suffice for 2-3 people, as it's canonically stated to have been designed for 3 person exploration. (presumably the helmsman, the pilot of the docked vehicle and the navigator/cameraperson.)

Though, a real 3 man cyclops would probably have a slightly larger area between the helm area and the vehicle bay to provide a place to sleep.
