Topper Summer silliness question

   Summer school holidays;  so it's down to the club to resurrect our aging Topper fleet with pump, soap spray and mastic. Having pumped the boat up well  it gets really nice and stiff. 

So here's the question. As most rotomoulds could be pumped up easily because of the construction method would it be possible to halve the amount of material in them design in some internal stiffeners and compensate by pressurising them to a couple of Psi before sailing to dramtically reducing weight and increasing stiffness? (lets ignore the safety issues for a moment)

 Paddle board manage this really well some are rated at 22psi, Wow!
