I've has something simular bouncing around in my head, for another purpose. I have several acres that I'm not doing anything but mowing and have been toying around with the idea of Hay/Mulch production for my ever increasing Garden . Since it takes so many HP to run a baler I wanted to come up with a way to do it with the Garden tractor. So have been looking at the way loose hay was put up in stacks in the past.
Your Fork concept could easily be adapted to a buck rake to pick up the windrows of hay and move them to the stack.
I'm also toying with the concept of making a dump rake for the rear to windrow.
