A friend of mine years ago ducted his R32 N/A intake into his cabin. Into his cabin. His thinking was when he turned on his A/C, the engine would breath in the cold air, get some performance, he ran without a filter as there was no need for one. Spiders and roaches would be squashed and burned if they'd ever get into the intake. But guess what? After the initial shock he got from insane intake noise from the startup rev, instant regret 30 seconds of driving it hahahaha, and of course, he had to return everything back to the way it was, but with a large hole in his firewall.
There are flexible stainless steel piping available, you could get the correct piping diameter with some coupling for your setup. No need to worry about piping angles. See here:

There is a panel under the stock air filter, if you would take a look at it, there is an outline for turbo piping. You can drill a hole there for either piping your pod, or to let ambient air in. There is a tutorial I think somewhere in the forums.
Do whatever you want to your car, the itch of not doing it when you wanted to do, can turn into a rash. Just don't get hurt or have anybody else hurt. And of course, be prepared for "I told you so, comments." Goodluck buddy.
