As far as I understand created items do not have any remaining ties to their recipes. Thus, a save game where a mod has been used is still usable by Sami for (non mod related) fault finding.
Thus, you ought to be able to change your statuette recipe for every dead dog, but you probably have to reload UrW for the new version to take effect.
I'd suggest just trying it out: Make a copy of your save, start your character, make a statuette, save, change the recipe, start again, make a new statuette, save and remove the recipe altogether (or comment it out), load the save and check whether both versions exist in parallel. Then you can discard the save and restore the copy (and restore the recipe before restarting).
