I am with mntnguide. I can't really think of an area where packing in would be feasible. Like you were saying, a lot of the areas with antelope are criss-crossed with roads, so if you hike more than a couple miles, you will just run into a road again anyway. Some of the bigger walk-in areas around here you can hike a couple miles in without crossing a road, but you can just park on the other side of the area to cover pretty much the whole area. The areas around Gillette don't take many points and have leftovers a lot of the time, so that might be an option if you don't draw somewhere else with more public area. I think that some of the walk-in areas in Natrona County are huge, like 20 to 70k acres. Some areas have a lot of development, but it seems like north of the highway from Casper to Shoshoni isn't as busy as south of the highway, maybe not. Those big walk-in areas might give more of the packing in/remote feel of a hunt, Areas 73 and 75 maybe? I didn't look at the MRS or anything to see how good of an area they are. Good luck!
