As a conversion, you can do the K&N filter on the end of the turbo and eliminate the air cleaner entirely, and install an independent oil separator as you mentioned. You will hear the whiz of the turbo when accelerating which is kinda fun, but you also get an overall increase of sound from the intake that can be heard in the cabin while cruising down the road(not so fun).

In the end, it's kind of a pick-your-poison situation.
THe problem with doing that (eliminating the whole K&N quality part of the argument) is that you would be sucking hot air from behind the radiator...vs cool air from the front of the car. Doing so raises intake air temps....reduces air density and that increases EGT's and reduces power.

I always preffer to draw air from outside the engine bay and the heat in it. But high enough above the road to eliminate the possibility of hydrolocking the engine if you hit standing water on a rainy day.

The stock air filter setup does exactly that.....
