Please. You're throwing an entire gender under the bus to lift up two men who don't need your help when the patriarchy conditions us to think mediocre men are more suited than prepared women.
And you're not even taking that seriously. Having a "bottomless well of empathy" does not make Erso a woman, like a woman, or anything stronger than his external genetalia. It does not count for anything.
This group is half women, at very least one of its representatives must be a woman. And really, if you're so interested in counterbalancing what other groups might be putting forward--more men, I'd assume. Both should be women.
