Have an ellipse that can be called an ellipse spar. Then have a keel spar. Have no other spars. Have the keel spar be approximately normal to the plane that holds the ellipse spar. To form the meta tensegrity base of the HG, have tendons between the keel spar and the ellipse spar. The ellipse spar would play several roles at once: queenposting, kingposting, control bar, staying camber of sail, staying reflex of sail, base for High Hat, base for Low Hat. There is no common kingpost, no common queen post; the functions of such are supplied by the tensegrity involved in this new BEF.
For tiny packing, the ellipse spar would be segmented and the keel spar would be segmented. Perhaps the segments could be airfoil shaped or teardrop shapped. Think also of captive arch for the upper and lower arches of the ellipse spar.
Tendons from ellipse spar may go to keel spar as well as to sail as well as to itself. Close: spoked wheel where spokes go from ellipse spar (rig of wheel) to the axle shaft (equivalent topologically to the HG keel). But then add lines or tendons to sail and other lines that go from ellipse spar to keel.
