With OKE we saw a winch arrangement allowing to rotate tethers without tangling them, with the possibility to change their common length by winding or unwinding them, just like yo-yo systems. But reel-out power phase and rotation in the same time looks difficult if it is possible. I don’t see how the swivel can be avoided. Do you think the three winches (with their hundreds of meters of respective tethers) should rotate with the cartwheel during the power phases?
