Doug, what we should be building is hybrid tiltrotors. We have axial flux motors now that are very light and compact, able to deliver high torque, perfect to provide a boost during take off and climb, where the engine is the least efficient, and we only need a smaller battery to do so that should be charged in forward flight.
Even in aircraft like these, one or two small gas turbines working as generators could be placed anywhere in the fuselage to power any configuration of propellers, although not ideal because of the extra weight. Still, one of these with a "booster" battery could eventually be cheaper to operate than conventional fixed wing turboprops, despite being way more flexible.
Furthermore, a single frame could support a variety of configurations, smaller engines can give you more range or fuel economy while bigger ones increase your payload capacity, and you can even remove that weight if all you do is short sporadic flights.
That's something we are plenty capable to do today, not 30 years from now.
