The JSA on "Earth-25"...

Expanding on the idea from this post, I think the Earth-25 JSA would be a pretty fun concept.

Since Earth-25 is for the most part completely gender-swapped, this means that the original JSA: Green Lantern, Sandman, Flash, Hawkman, the Atom, Mr(s) Terrific, Doctor Mid-Nite and so on and so forth would all be women.

The concept basically centers around the idea of "Rosie the Riveter in a cape".

Criminals don't sleep just because the menfolk are off to war, so it's up to the ladies of the JSA to step up and get things done, clearing the streets and keeping the populace safe during this troublesome time.

The round table members are all women, but there probably are male affiliates as well. I like the idea of the secretary of the group being a man (though the one downside is that Hippolyta remains female in my conceptual Earth-25. That doesn't, however, mean that others can't step up. Heck, Pa Hunkel is probably roaming around whacking people with frying pans.)

I personally think "Sandy the Golden Girl" would be adorable.

Most of the villains translate pretty well to the opposite gender I think, particularly the Shade, who'll be equally as fabulous as a woman as he is as a man. The one character I'm uncertain of is Johnny Sorrow. There were certainly female silent film stars who never made the transition to talkies, but the key to Sorrow, I've always felt, is that on some level he's never stopped playing his old movie roles. Over the top villains or tragic, dramatic heroes, depending on how you look at them. Women played different roles, and while a Jeanie Sorrow embracing whole heartedly a diabolical sexpot role might be interesting but it's a tad more pedestrian in comics I think, and I'm not sure it captures the unique creepiness that Johnny Sorrow maintains.

The real advantage to the female-JSA is that there's a built in reason that they would have fallen off the map. It's the nineteen-fifties and all the post-war conservative backlash favoring strict gender roles would have made it incredibly difficult for the women to publically superhero. There's the perfect excuse for the JSA to not be active by the time the Justice League is formed.
