I get that some people relate to characters on a very superficial level, e.g., "the character's a girl and I'm a girl so she's relatable." Of course, there are a lot of deeper, more meaningful factors that make a character relatable.
But we're not even really talking a out characters, just namless "extras" filling out squads. I'm not sure why they need to be relatable in the first place, at least not on some kind of one-for-one personal basis. If you can't identify with a Rebel soldier fighting against the Imperial tyranny unless X% of the sculpts are female, it may very well be some kind of political hang up.
