venting underbody air into trailing wake

i read on here somewhere about venting the underbody air into the trailing wake. i was thinking about drilling a 6in. hole in back bumper behind each wheel. maybe hot glue some open mesh on inside of bumper to help with looks. wondering if anyone has thoughts on this.
