Sure, but the question isn't whether you can, it's whether you want to. General aviation's accident and fatality rates are atrocious.

Have you considered consulting for Boeing and Airbus and telling them that their fallbacks are bloating their planes?

Boeing et al are forced to implement all those safety systems due to regulations.

Then go consult for the FAA and tell them those safety systems are just bloat for aeroplanes.

I'm not saying they're bloat. They're a tradeoff between cost (man hours of work) and lives. They've increased the cost of small planes tenfold but have saved tens of thousands of lives.

Have you also taken into consideration the death rate in smaller planes, much higher than commercial craft. The moment you attempt that with a 'high capacity' craft you'll suddenly find yourself regulated out of existence by a book written in blood.
