Well I gutted my PCV valve and ran the hose to my catch can. I then custom mounted a small breather on the can and blocked off the vaccum nipple on the IM. I hope I don't get owned by a misfire. It should be good for keeping some blow by vapor out of the combustion chamber.

I am now running a single hose from the valve cover nipple to the can with an open PCV valve. Essentially, the PCV valve is just a stopper at this point and all my crankcase gases come out of the valve cover into the can. Some time in the future, I plan to either get some -AN fittings tapped into the front of the valve cover and run to a can or run block fittings to the can after removing and plugging the breather box like how the Endyn can is setup.
So far, the way this is set up is just fine. At idle, I can see oil vapors coming from the filter on top of the can. I have the can mounted to the battery box via a hose clamp loosely holding it on. Ghetto but functional.
Gutting the PCV valve is unnecessary unless you are boosted and want to do it ghetto-style like I did. Your PCV valve should be open at all times unless you have a misfire. The positive pressure will close it. It is problematic during boost because anytime the pressure is positive, the PCV valve is closed, so those gases remain trapped when they need to be evacuated causing blown ring lands.
I don't catch much oil in my can. I have yet to empty it, so it may not be as efficient as I think it is. The way you have yours set up is perfectly fine on a naturally aspirated motor.
Sorry, I can't be more help. It is one of those things that I know I should do correctly, but money is an issue and the fact that this setup is working just fine. Once/if I blow out my ringlands, I will do things the "correct" way.
That's interesting when I look at the Helms diagram on the PCV system, it shows fresh air being drawn from the intake arm.
