Toward the worst AWES

Yes, interesting. So complete gyrokites could perhaps overcome this issue, their respective rotors being not dependent to the main line. Or a large lifter kite would be required if rotors are dependent and perpendicular to said main line. Or perhaps other solutions like on your sketch with a gap of the segments of the tether allowing significant angle variations, or on my sketch below (I put again) without gap but with limited potential of angle variation.
