Travis; I'm a straw bale builder, hence I'm not excited for the trend of round bales(!) However, the one thing they have going for them is that they roll! This summer it took 4 people to roll a couple up on our trailer, and last week I moved one some 100 meters alone... Even if the ones you have are too wet, you should be able to do it with a vehicle or simple a long stick for leverage and a block below it.
In regards to your drawing; If you choose to do it, I'd suggest digging a good wide ditch for the bale to get a foot or 2 deep into the ground. It will create stability and make it easier to cover.
