Take twelve blades, run the generators as motors and, uuuh, attach an 40GW CNG power plant? Suddenly clearing out thay landing strip for Windrunner does not seem all that hard ;) The least-unrealistic approach to go full Munchhausen on getting rotor blades airborne might be assembling them in pairs or triplets and then lifting the contraption with some form of flying tugs that attach near the tips and pulling them into rotation once sufficiently clear from the ground. Like a tip jet rotor tailless helicopter, but with external propulsion units, and powerful enough for static lift during start and touchdown. Would still need per-blade pitch control through the rotation cycle to compensate for the lift difference between forward-going blade and backward-going blade while non-stationary (or compensating wind). Still wildly unrealistic, but other "use the blades to fly themselves!" are even further out I think.
