As appealing as bow hunting only would be it doesn't address the problem of access in the suburban area's where the largest concentration of deer density is likely to occur.If something like this were to happen you would also need the political support and the community support to have it work favorably.
Unless you have a county that is extremely suburban I don't think it would be a good idea at all,meaning the consideration should be one of safety not exclusion.
I also very much like the diversity of rifle hunting and wouldn't want to give it up.
