The rotors do not generate lift by themselves, but by the lifting kite which ensures their angle of attack (which is lower (= more lift and less power) for the rotors close to the kite) and the average angle of elevation. The higher the angle of elevation, the larger the lifting kite area.
Also it is not so easy to obtain rotors ensuring both torque and lift. So perhaps rotors ensuring torque and power should be settled close to the ground station, and rotors ensuring lift close to the kite.
If you really want harness altitude winds for power, then only the lifting kite is used, which incorporates a yo-yo system in aligned or crosswind flight.
