I use to have a HF and bought the Pat's and really like the them so well that I installed a hydraulic toplink 

THAT'S THE WAY TO GO!!!
I decided bushings are cheap and once they go on they never have to come off of the old implements and stay Cat 2 ready.
I guess your view would be to just store the Cat 1 to Cat 2 bushings on the Cat 2 tractor and "bush up" on the implement as needed?
2. More head scratching comes from looking at the RFM. It is designed so the toplink attachment to what I'd describe as a swinging clevis presents more of a challange. If that were eliminated it looks like the RFM won't be able to follow the ground contours. With the swinging clevis arrangement the mower deck can ride over the ups and downs. Eliminating the swing action it looks like the deck will want to remain on the same plane as the tractor, raising the rear wheels off the ground when cresting a rise and rainsing the front wheels when coming to the bottom of a hill. How do you deal with that? I'm pretty sure I could come up with an arrangement that would still allow movement but am not anxious to redesign the mounting frame.
