To be honest, I don't think it would matter one bit if they combine it during the shotgun season. If they open a special season for it, it most likely would be during the bow season so it might take up a week or so, again shouldn't matter.
If you think about it, the slug guns we use today are just about rifle like as you can get. My slug gun shoots 400grain sabot slugs a blistering 1900 fps and I am zeroed in at 100yds. I can pretty much kill from0 to 200 yds without having to hold over or under.
Becides, I would love to break out some of my rifles!

Since I moved back to the midwest (years ago) only the smaller calibers get a work out (coyotes and such)
If they do add in a rifle season it will be short and limited so I don't think it would hurt at all.
