I'm torn. On the one hand, all of this is a brilliant reinvention of Wonder Woman (especially when you compare it to something like The Ultimates, where the big ideas are stuff like "but here, Jarvis is GAY!"). On the other, something about Glory and Eurydice being closeted lesbians rubs me the wrong way. Perhaps because there's no shortage of lipstick lesbians in comics, to the point where actually having them be out-and-out (sorry) lovers would be more subversive and refreshing than "teehee, they might be gay!"
Certainly, there doesn't seem to be anything in this proposal that precludes the idea, except for the assumption that them actually being out and would be too "pornographic" for the "innocent" tone Alan Moore is trying for.
