Might be possible, but is even more compicated than skysails’ (I assume you meant them) system, which might have had some issues. (We don’t know for sure, but the original company did go under)
The kite was docked using a separate line just to get the valve in the right position, I think.
Maybe this would be the case here, too. The valve is at the back and there’s always a line going from there to the docking station.
If one has the packing station at a large enough distance I don’t think it’s neccessary to adjust the angle to the wind exactly. The winch can pull the kite up. Landing will probably be much more difficult.
The future is said to be rigid. Would make automation much easier. Just do it like zipline and let the kite hang there (or lower it into a container). To launch just tighten the winch line and release the hook. (The hook would have to be designed to allow for only two degrees of freedom, so that the plite doesn’t launch into the ground) Might even be possible for unpowered drones.
