Oh - something you obviously haven't accounted for - vacuum will take air from the area that resists it the least.

In this case, you're still getting the warmest air that the filter has access to, since heat rises (and will actually vent through your hood now, due to the venturi effect that the bowl half is going to create). So you've basically created a "harder than it had to be" WAI.

You can't say that you've actually experimented with CAI/WAI because you haven't. You don't have data sets, you weren't even attempting to control the IAT's, let alone monitor them. Until you've done those things, this is just a joke.

Why not spend all this time on making a few bucks helping someone out so that you can go get a SG-2 and actually test your modifications?

You've also added approx .5 SqFt, by the looks of it, protruding into a normally smooth area. Yeah, you just screwed up your aero.
