I know this sounds kind of bad but..... just do it in a way that is easiest to revert back to what you currently have... this car will never see another smog ref once approved. It only has to drive to the smog station and back home in that condition.
Too be honest, I have that set up (hose to tube extension that the air filter attaches to) and have no problems in 4 years. I have a breather on the rear valve cover area though. No real good pic. Oh, it's a honda but exact same issue.
