I wasn't aware you could add cams to this type of bearing block

Look at 2791's recent drivetrains. I'm sure Chris Picone can elaborate more on their processes, but they run a C-C WCD variant without blocks and haven't experienced any problems that I'm aware of.

And those cams were invented for that kind of bearing block.
