I'll see what I can do. I printed out the parts for testing and will take a look. I'm also considering instead of using the cam-lock, maybe go with bolts and wing nuts. I have an idea where the bolts would replace the latches and then you could tighten the wing nuts up snug. This would give the clearance you are looking for and maybe be more secure. If you could draw out a sketch of how you would like the part curved I can make a version for your testing.
