Given the material chemistry constraints on output/capacity/weight will govern any innovation in this field, I'd like to see some out-of-the-box thinking. For example, "in flight" hot-swapping mid-air of rotor legs with recharged replacements on demand at some rendezvous point. In fact, you could swarm a standby entourage of rotors on your journey which wouldn't be subject to the frame+passenger load. I'm sure there's some optimal creative refilling strategy.
