I found this Van Craft has some interesting rotors that seem to have the composite rotor hub like skywheels and metal blades kind of like what you described Madman Mike had tried out.Skywheel users were very fond of their blades, misinterpreting their behavior.
The noseup pitching in an upward gust is believed to be the result of high lift and the extended float during landing is believed to be the result of high inertia rather than unstable blade twist that occurs during a load increase.
I’m not sure how the chordwise balance could be corrected; the skins are quite heavy and the spar is a solid aluminum extrusion. A brass spar?
A gyro owner who went by the name “Madman Mike” used extruded aluminum 8H12 blades plugged into a Skywheels hub with satisfactory results.
