Your set up looks fine... need to machine the down turn or ad a diverter, spacer, snoot...ect. A wedge might not be enough.
I have this mini place with original powder lightly used and has a 3 1/2 degree pin with about 1/2" of droop. This would replace your nozzle adapter and lower the thrust line as well move it out giving you some reverse.
You could put a small block of aluminum under the cradle to get the feet at bowl. Measure it now to get your degree from keel or just the thickness of spacer above feet. I'm just suggesting what I see in your pic of the cradle and has nothing to do with reverse deal.
