The SGT style cat. 0 rear lift uses the 5, 7 & 9 o'clock bolts (on your pictures) to hold the lower arm mount. So those brackets would be pushed out by the thickness of your plate. With your plate, and the lift arm brackets, it would need a 4 1/4" long bolt. A 4" is called for with the arm brackets alone.
The previous owner of my 1572 had made a "U" shaped bracket to hold the rear end when they broke off the bolts that connect to the frame. It did not not work with my 3 pt (from Bill Ruegg), because it interfered with the mounting of the 3 pt rockshaft bracket, and the square "U" was blocking the area for the arm pin to be. Where your solution extends forward to handle moment only (and I have since extracted and helicoiled the top holes), it seems that it should work just fine and not cause any of these interference issues.
Now if someone was clever, your idea could be combined with the lower arm mount brackets, to leave the arm brackets in the factory intended location, yet add that better moment connection to the frame. If you don't take offence, I believe that I your idea and my welder will be put to use shortly.
My other option is a cast iron rear end, but that does not work with the diesel tank (there is a thread going on this now). I do believe that another aluminum rear end without reinforcement will fail again, so I do not consider that an option. 5 minutes with the John Deere Model 30 hydraulic tiller breaking ground is all it takes to loosen those bolts.
