Randomly found your account through my friend sending me your IDV Annie skin (which is so good btw), there's a never-added IDV survivor from the beta called 'Mountaineer' (or well there's no official known name) that I think would look really cute in your style if you want something no one has ever done before lol
There's a lot of great OCs! Some PMCers put them in collection while others don't. But it's not hard to find one that really speaks with you if you look around lol
