I don't think coming up with female versions of male characters (at the same company) is necessarily copying or unoriginal. Just trying a different direction.
Now, Midnighter of The Authority - he's a Batman clone who just embraces all the wink-wink-nudge-nudge homoerotic subtext of the 1950's-60's Bat family comics (the editors were really naive then, weren't they?) Him and Apollo, it's just playing out the whole "Yes, Kirk & Spock are gay!" fanatsy. 🙄
