You want the bad news now or do you want to find out on track?
If there's any catch can to
attempt to implement with an OEM PCV, it's the BMS. The hose runs are kept as short as possible so it doesn't delay (as much) the TIP vacuum from drawing on the crankcase where it's actually needed. I am still not entirely sure it'll work properly with your setup.
Every long hose catch can system with OEM PCV system I've seen has had major problems with either A) still smoking or B) filling the can insanely fast.
Like we have a local guy that had an ECS can (which is functionally identical to what you have) that completely filled up over 4 autocross runs.
Any plans to come to VIR in February? We can put a gauge on your car to know for sure what's going on.

I'd be surprised if you get "enough" vacuum draw to let an OEM PCV work properly with that intake setup. The only real options are MK8 PCV with the Venturi (requires an 034 TMD, or tap your charge pipe between turbo outlet and intercooler for a hose) or a full PCV plate system like APR or VWR (I'd personally do APR between those two)... which does not fix the root problem (pressure in crankcase, inconsistent vacuum draw), but WILL fix the smoking because they draw vacuum/vent via the valve cover, not the oil pathway in the block.
Not sure how far you are from Newport News, VA... but if you ever want to come up this way to go to Busch Gardens or VA Beach or whatever tourist shit, you're welcome to stop by and we can get some data on your car to make sure it's straight.
