If this is a thing, and 3Z actually is making this, I'm thinking:
Major in the Thermoptic suit, trenchcoat, and goggles
Batou in combat gear, EX having the trenchcoat duds from the club and a cyber eye'd headsculpt.
Maybe, somehow, a Civvie Major. Which is what I would really like to see. But it couldn't simply be an add-on piece like an Ex. It would have to be a separate figure. I guess it could, but assuming 3Z did a bodysuit for her, you wouldn't want to risk staining it with dark clothes.
Maybe that's best option, and we just kitbash with a spare body. Maybe they can knowingly assume this and throw an angry sculpt in as well.
If they can make figures from The Wall, they should be able to do this.
