You can use any mixture of flour that you like. I haven't tried gluten free because I don't have to watch that, but I'm sure you could substitute a gluten free baking mix for all the dry ingredients except the nuts and chocolate bits. If you don't like almonds, use walnuts or pecans. I found this to be a really good use for the coconut pulp, but you could use any nut milk pulp in this recipe with really good results.
