A simpler solution might be to add blocks to the trailer suspension to raise it an inch or two. But in all honesty, I wouldn't worry about that little of nose high. Only six inches of bed rail clearance would be more of a concern for me. I have 8 inches of clearance and I have been very close to hitting the bed rails on unlevel ground.
I also have the B&W companion hitch and found that the rig seems to tow much smoother with the hitch on the lowest setting, so I leave it there. Just have to be aware when backing into sloped sites and unlevel ground.
