Honestly, instead of wasting Gwendoline Christie in NuStarWars, they should have cast her as Captain Marvel/Carol Danvers instead of Brie Larson. Mainly because Gwendoline can play Stoic Badass With a Heart of Gold pretty well and make herself likable (I mean, just look at Brienne of Tarth), and from all the stuff I've seen her in, she's a GREAT ambassador for the stuff she's in and for promoting it.
And ironically enough, in this case, Brie can't even back herself up by saying "You just want me out because you're sexist and I'm not a conventional sexpot!", because she'd just look like a cunt because compared to Gwendoline Christie (who I think is a beautiful woman, personally), Brie is a conventional beauty.
