I do not think a carousel is necessarily a viable solution, having only written that several kites can be connected.
Both tether drag and weight are (perhaps unequal) issues in regard to viability. A fairly simple (but not perfect) way to estimate the tether weight issue is to add the tether weight to the wing weight in order to obtain the new wing loading.
At short tether length, we can guess that the weight of a rigid wing alone becomes a limit as it scales up. E.g. (p.3 http://www.energykitesystems.net/FAA/FAAfromMakani.pdf) Makani M600 expected specifications: 1050 kg wing mass, 440 m tether length, 250 kg tether mass [electrified, so heavier].
That said let us try to reply to the topic question. I would like to say that growing up is an obligation depending on the length of the tether and the space occupied, to avoid the risks of collisions that “networks” of small artificially connected units cannot prevent. Indeed, such units without a network connection would work just as well (or poorly). Do we see planes or wind turbines in smaller unit connected in networks? The answer is no. Just because the word “network” is fashionable doesn’t mean that it leads to a workable solution.
Let us think rather of a modular realization according to which the elements contribute to the unity of the whole. Perhaps also lowering the cantilever effect of a classic wind turbine by using airborne elements (like KiteX does) could lead to a viable solution.
And also a giant flexible power kite towing a boat seems to work well.
