This isn’t really right. For a start no stationary kite will be making power.
Yes a flown-cone moves around with the wind and covers a 360 deg field volume.
So being more efficient with the length of that cone or cylinder as it rises and grows is important.
The more power we can generate per length the less material we have to use, the less land we affect, - Lower LCOE, EOREI…
OK
A more efficient cone or cylinder packing might be able to fly a long line beside other cones or cylinders.
Cool.

Needs lots of control.
A rotary downwind line still cuts a cone, and can have multiple generating elements on it. So it may be generating using many blades per length … A multi blade yo-yo type can possibly also generate using multiple blades on a single line. (See @rachel Optimal control of stacked multi-kite systems for utility-scale airborne wind energy or Kiteswarms) Also a rotor can be used to drive a yo-yo design
Scaling and spacing - That’s an issue, - you’ve just recognised it. It is important now. It’s not a good idea to ignore it. It is important now.
You can’t just sell 1 solar panel stacked on top of another… recognising that before deciding to make solar panels would change how you started to design them
