I toyed around with that very concept a few years back using the 575 I sold. There are a few producers that do it presently but the issues are many for me at least. One, I'd need the room to set up a baler and power it, two I'd need a way to 'unroll' a round and feed it consistently and uniformly into the square baler, three, there becomes the issue of handling and storage again and four the most important part with me at least would be leaf loss from re-bailing the rounds to squares. I have the indoor room but the physical properties of such an operation are huge. I believe there is maybe one of more outfits that off a setup like that to purchase (or you can fabricate your own which is what I considered but decided not to. If you run mostly grass hay, leaf loss is a non issue. I don't. If I were you and you want to go that route, I'd take a had look at a 'Bale baron' which makes small squares and packages them in quantity (like your large squares but in small squares combined into a single large square that you can take to the barn and break down at your convenience and sell individually.
