It is going to get Really really hot and I would not do it. Honey really does not add anything much other than label appeal to soap. I would also change the percentages to 90% CO 10% Castor
I would give it a go. I added 1 tsp ppo in an OMH salt bar and didn't have a problem. I just lightly covered them to avoid ash. I even added some finely ground oatmeal.
