Whatever you do, DON'T PUT ANY URINE SCENT IN YOUR SOAP! As others have pointed out, the Doe in Esteres or Bull in Rut type scents are to attract the male of the species to the area. If the scent is on your body, the rutting bull elk or buck may think you're either a soon-to-be mate, or another male competing for the girls attentions. Either way, it's a situation to be avoided and very dangerous!
Another thing to consider is the formulation of these types of scents. They usually say something on the bottle about avoiding skin contact. I'm sure they aren't stable in soap batter so you don't know if you'll end up with weird, stinky soap or creating a volcano.
Since my DH is an avid archery hunter and always in the field, he prefers unscented, uncolored soap on his body. He uses PT on his hair though. He also uses unscented lotion and deodorant. As for his clothing, all hunting attire is washed in washing soda only, hung to dry, then put in certain containers to keep other smells out. When he has a big hunt I'm forbidden to cook bacon, lol.
If your hunters want scent, stick to EO's that are found in local flora where the wildlife live and keep it light. Occasionally he'll use soap with cedar, juniper, pine or rosemary, but not often. Since there really aren't any difinitive studies on how things smell to wildlife, it's safest to stick with as few scents as possible.
