What are you riding/hunting off of?

jsh, you can buy saddles that are made with the rigging the way you are talking about, my saddle is just an old trophy saddle with a full double rigging I had won and used till it was pretty torn up so I patched it up and made a saddle for my mule out of it, I ride 4 nylon latigos on all my saddles rather than using billets and to keep the cinch from rubbing the mule I take the back latigos and pull the cinch ring back with it and it keeps the back of the saddle down good as well, works pretty good for a colt you are breaking too once you figure out how to position it. I don't ride a back cinch nor breast collar on my mules, the back cinch can catch a wire when jumping if the mule misjudges by a fraction and "I think a breast collar restricts their reach a little" plus the fact I have never had my saddle try to come off the rear in real steep country or when dragging a hog, the front cinch being forwards of the rib spring and belly curve. Some folks ride a wide mohair girth for a back cinch on a mule and put it way back toward the flank behind the curve of the belly rather than a britching or a crupper. You can also buy a saddle with "mule bars" in it since a mule and a horse are made somewhat different but I have not had any trouble with the quarter horse bars when a mule is padded right. Lots of ways to rig a saddle for a mule whatever works for you in your circumstance is what is best.
