Halo to me has always been one of those games where gender didn't matter. I've never felt uncomfortable playing a female in other games, and all females in Halo are just, y'know, people. They're not "girl power!", they're just strong characters who happen to be women, like how the strong male characters just happen to be male. I can't think of many characters that are written to be explicitly feminine, besides Cortana who's obviously meant to be a mother figure. Palmer's "Attention Ladies and... other Spartans" was the only example I can think of it where the forced female power trope is force-fed to the audience. It wasn't necessary, it just made Palmer look kind of petty. It wasn't needed because females in Halo are of equal power and respect to men.
So for the topic at hand, go for it, it'd be nice to get some more variety in characters.
