Haymaster 8 bale grapple...can it be converted to a 10 bale with a few more hooks?

I just bought a almost new hay master 8 bale grapple for $1500(pretty good deal I thought beings that finding a used grapple is very hard). I have a 10 bale hoelscher accumulator I bought a month ago. I figure that since the hay master accumulator sets bales with the strings down and the typical bale is 14x18 that if you set them on their side, 10 on their side would fit fine. All I should need to do is add a row of hooks and be good to go. Anyone ever done this or have any experience with doing anything like this? Any help or thoughts would be appreciated!
