Savonius AWE kite?

There are some drag devices like Magenn, with some variants about Ideas for scaling up AWES based on a tethered airborne rotor driving a rope drive.

But real Savonius designs are differently shaped, in S with a hole between the blades to increase efficiency, not comprising an inner inflatable cylinder, like on the photo below, from

Do you see a possibility towards AWES with a rope-drive transmission? I think even with a low power coefficient (0.15), this is perhaps a possibility if it can be light enough as it scales, undergoing only the weight of the frame. And stacking unities could be possible in AWES farm in bumper car mode
