Mothra on a ring allowing facing wind directions has been described. Its two anchors could be two winches in yoyo mode as described on Scaling by size - #43 by PierreB, or two pulleys-generators as for the figure 5 above, the problem to overcome for the last being the half turn as reversible wings do not exist for what I know.
Other variants can be found, comprising how build the ring and the mobile parts (winches or pulleys with their respective generators) because they undergo a huge traction from the kite.
