Commercially available Mayordomo chocolates (both green and gold) simply contain, in addition to sugar as the main ingredient, cacao beans, almonds, and cinnamon. I see no reason why you couldn't use a high-quality unsweetened chocolate and mix it with ground roasted almonds and cinnamon. I've never tried this since the standard Mayordomo offerings suit me just fine, but I'd bet in something like a black mole, which doesn't contain much chocolate to start with, you'd be hard pressed to notice a difference.
