It looks like some possible progress.
Some observations and questions, then a suggestion:
As the “future proportions and details vary greatly”, the diameter of the Anchor Circle should be (about 10 times) far larger compared to the kite size, that in order to allow the kite making fast and long crosswind trajectories and sweep more.
The FIG. 5 part seems to be within the installation, going from the two pulleys toward the kite, the pendants and the Anchor Circle being the added parts.
So the two pulleys look to be on the ground, not in flight, is it right? Are they anchored on the ground? If yes you have to move the two (FIG. 5) pulleys when the wind direction changes, while in the same time
you should detach the pendants from the anchors to reattach them to the two appropriate anchors. How is it possible without human intervention?
Suggestion: removing pendants then settling the (FIG. 5) two pulleys directly on the two anchors, installing a circle line connecting all the anchors. When the wind direction changes, the (FIG. 5) two pulleys slide through the circle line, from two anchors towards the next two anchors. Each anchor would comprise a mechanism to retain then release a pulley, leading to a possible automation.
