Honestly, I'm surprised they don't already. Folding karambits seem to sell really well, they are constantly selling out at places like BladeHQ and Knifecenter, even the $150+ ones like Emerson and Fox. Plus they are generally considered more of a tactical/self defense knife than a utility knife, which is a niche that CS really markets themselves towards as well. I would bet money that a $50-80 folding karambit with CS's level of quality would sell like hotcakes. Not only are karambits pretty popular in general right now, there's basically nothing in that price range either, you either spend $15 on junky Tac-Force/S&W/United Cutlery stuff, or jump up to $150 for Emerson/Fox. Okay, there's the 5.11 CUB Master at $100, but even with that, in the $50-80 range CS wouldn't even have any competitors!
