Show me your vented valve cover options

I am designing my crankcase breathing system, and I am deciding how I want to develop my oil fill cap portion. I want to vent to a catch can rather than VTA directly. Have you seen anyone use something like this on an MS3?

Of course, there are options like below, that I can put a 90* AN fitting on, but I'm feeling creative. It's not a have-to thing for me, but I got curious when I saw the one above from a K series.

 

I don't know what size the orifice is within the valve cover or if it's even reachable but on Miata's we can remove the baffles and bore the hole out to allow for extra flow.

That may be something to consider if you can find a spare cover to mess around with.
