Yes you could but that would then get in the way of the other procedures/ vectoring.
Just bung a line off from the end point of a star to some place that they arn't going to get in the way and thats your procedure designed. It won't cost a fortune.
I agree its political as most airports and airlines don't want slow IFR traffic getting in the way of the commercial inbounds. They will suffer it enroute because the levels being used in general aren't the ones they want. I think most will put up with getting you to the end of a star or getting somewhere visual then hopefully you will dissappear of to some other airport without any approach aids. If not you are stuck orbiting until they have a hole to get you in.
