I dunno, none of that makes any sense to me. You want to make it where people can't hunt them, so they can use a more expensive, time-consuming and labor intensive method to dispose of them. Do you think that is going to encourage more people to utilize trapping than already do now? What benefit is there to the theoretical "former" hunters?
I personally think your proposed position would simply lead to an even bigger explosion in the hog population. We are their only natural predators - imposing more restrictions on humans hunting hogs is going to lead to more hogs. They are voracious, they are rapid reproducers and have no essentially no natural predators in this area. That would be a recipe for disaster, especially for agriculture.
Just my opinion.
