Not familiar with the rear PTO units you are referring to.
I measured the clearance to the transmission lid and the shaft and I think there is room. The Lovejoy coupler is 1-3/16 dia, and there is room for an almost 2 inch dia coupling.
I see that the two shafts are separated by four or five inches, and I thought about that. Plan was to create an extension to the pump shaft to accommodate the Lovejoy coupling. I am concerned about supporting that shaft but the pump shaft is 1-1/2 inches long and I thought an extension shaft could be adequately supported if I used all of that length inside the extension.
But I'd rather not deal with it if a solid sleeve (as I used for alignment) would work. Other than a lovejoy or similar device, I don't know how to get flex in the pump drive. The only U-joints I see are low speed or very expensive so that doesn't appear to be an option either.
If I created a drive shaft from the hydro to the pump with a sleeve that was a bit loose, and pinned it to both shafts so it had a bit of wiggle to it, that might work? Is that what you mean, Jon?
