Instead of capping off the breather, run the vacuum line from the intake manifold to that. Then run the 2 ports on the side to the valve cover.

You could always set it up like you made the diagram, but instead of capping the breather, you could put a kracka vent in so under vacuum the breather is closed, but under pressure in the catch can, it opens. Like if you are getting pressure from the valve cover.
