Seriously, though, it makes sense from a logical standpoint for the visual differences between the genders to be subtle. I read somewhere that research into real-life combat shows that, to be blunt, boobs get in the way. The most effective armour for women flatten the breasts and they've got some impressive military-grade binders that can completely flatten D-cups. (Seriously!) So armour that emphasizes the breasts like in the above Doomgirl pic is actually rather impractical.
Anyway, I mostly wanted to speak up for the women on this site (who are mostly absent just like everyone else) who play this game and who I know would want some representation.
As one of those few women, I wholeheartedly second this. I mean, just look up modern female combat gear, it's pretty much the same as the male versions. In video games, Dark Souls has some really good examples of how to do armour for women. Captain Phasma from the latest Star Wars film is another example of how to do female armour well. If Jupiter Hell had stuff like that, that would be awesome!
