The gas tank IS under the back seat cushion; to gain that space would involve reengineering the gas tank, the sensors, the floor pan, side panels to match, the back seat so if you did have a passenger you would have to have a way to not have them feeling like their sitting in a hole, the frame.
I have a very simple fix for more carry capacity; external saddle bags.
Side bags hold 1.5 cubic feet, X 2 = 3.0 cubic feet
You can also do a tail bag, or a Aero box on top of the hatch lid.
