I'm having trouble visualizing what you're proposing, Longshot. The stock intake tube is really big enough once you get rid of the restrictive snorkel. As long as the intake cross section area is at least equal to the throttle body area, you should be getting improved breathing.
However, take pictures and show us what you do. We'll be happy to poke holes in it and critique you to death!

Hope you understand I'm joking a bit - we really don't seem to do that sort of thing here.
I think MY problem may be I don't understand the commercial CAI setup you are talking about.
