I've seen deer bed down in old utility sheds, under trashed out flatbed trailers, around broken windmills. I think any blind with some soundproofing will work and worrying about "edges" is unnecessary. Just get the building in the location asap and leave it be so the critters can get used to it. A little extra feed wouldn't hurt.
