You can't just simply replace agave in recipes with sucralose or palm sugar because they will completely dry out and be gross. Also most recipes using coconut flour need agave to help as a binder so not only would I run into problems with the chemistry of the recipe it will not taste as good so using say oil or water to replace the agave will not work out the same in the recipe.
