Well, while this is likely not the 'proper' answer, I transplant things all season long. Just 2 weeks ago I pulled up 2 gigantic hostas (that were in bloom) and split them down into 19 (yeah nineteen!!) plants. All survived without a hitch,and are still flowering! I have moved rosebushes (shocked it, but it is now 2' high and happy in its new home), bushes (blue spruce, mugo, etc), every perennial that annoyed me in its present place...you get the hint!! LOL!! You are right, spring and fall are the ideal, but I say if you are not happy with them now, move 'em. Water them like crazy for 3-4 days, and I bet they will be happy in their new home. Hope this helps.

Same here - just cut down with a spade a ways back from and all around the rootball, so as to get all of the rootball without damaging the roots too much, and then water well (and frequently, if it needs it) in its new spot. If you're moving an entire plant, and don't do too much root damage, it won't even know it's been moved.

I agree. Go for it. I know a "tree guy" (landscaper) who says that Fall is the best time to plant trees. I would think bushes would be the same.
