There actually are two or three viable variants for her that would allow Mattel to reuse the tooling.
I do want a Light-Spinner. I'd even take an alternate colored Shadow Weaver; maybe one in all black with the red emblem?
Or maybe an Empress Shadow Weaver for the classics canon when Skeletor defeats Hordak? She could oppose Skeletor for control of the Horde. She could resemble one of Emiliano's or Gbagok's concepts for Shadow Weaver.
