"Very nifty group. I especially like the fact that, contrasted with most of the groups put forth (including mine), it seems as though the vast majority your team will be able to make it into space for the final battle (this isn't a dig at anyone - please do not take offense ). "
That was a consideration.
Also, the Legion members from the future are bringing calibrated flight rings for everyone, so everyone who can't fly unaided now can. Also, they'll be able to survive in space, communicate with and keep track of each other.
"The only question I might raise (and again, since this is entirely your team and thus creative license and creator's prerogative kick in) is that it seems that the entirety of the team is "a whole lotta hurt", if you catch my meaning; granted, you have a story forthcoming which may, in fact, answer this, but do you have someone in mind to act as the support/"administration" of the team? You may not and that's entirely your prerogative again, but I was simply wondering if you had thought about it. "
This is entirely a strike team, with Photon and Power Girl as field leaders, designed to strike directly at the heart of Lady Styx's operation.
The way I figure it, every female hero (and probably most of the villains) would be involved in some capacity, either by fighting Styx's armies throughout the galaxy or by acting as admin, as you mention.
