Yes, a few hours in a melanger works for all the dry things I've tried so far (nuts, freeze dried fruit, kale chips, oats, caramelized sugar). Also, oil based flavors such as food grade essential oils are concentrated enough that you only need a teaspoon or two per kg of chocolate, I use orange and peppermint at christmas https://www.lorannoils.com/1-dram-size
Changing the formulation of the chocolate isn't that big a deal because there is so much variation in chocolate anyway. If you wanted to infuse cocoa butter and add it, just use a chocolate that's lower CB to begin with, not a 35% CB couverture. I've been working with a company who wants to produce an herbal supplement bar, they bring me their dry mix and I grind it into chocolate. My instinct was to add a lot more CB because I was worried about the dry matter making it too thick, but since I'm using a very fluid, high fat Felchlin chocolate already, I really don't need to add much. In contrast, another chocolatier I've worked for was using a couple formulas of Guittard that were just super thick, I added CB liberally to make the chocolate more flowing for molding and closer to the couverture I'm used to.
