I'm not sure it would work. MT lions aren't carrion feeders. Even their own kills they tend to leave after a day or two.

On the other hand they will come in to calls. So if a lion was in the immediate area and had no competition they might go to a fresh kill.

You would need a source of fresh bait that they would eat. Their favorite food is deer and you will find that using a fresh killed deer for bait is probably just plain illegal. Then multiple deer kills would increase your jeopardy by violating bag limits.
