All the way back to carburetor engines the air filter housings have had that metal, anteater type intake. If it was good enough for my dad's 396 turbo jet to breathe through, it should be great for a Porsche with the factory cold box set up. I experimented like you then settled for this compromise, I removed the tray cup that partially blocks the intake opening. Then I polished it with a variety of methods which I'm sure is totally subliminal in effect but hey placebos work all the time. Anyhow, it's my take on the intake.
When I had the intake vent out I was thinking of doing something similar to your setup. I was also considering getting another snorkel and reshaping it into a more free flowing air horn but it would require alot of flow modeling and bench testing. I used to do alot of CFD in grad school but for the small gains that would yield, I'll just stick with the stock snorkel.

Haha I was going to get another snorkel and chop it shorter. The idea you had would be a fun winter project if you had all the necessary equipment. I have to think Porsche already has that covered pretty well. I really didn't understand the function of the piece I removed, that thing that looks like the dip cup they put holy water in. It certainly looked to me like it was blocking the inlet. As for cones, I think anything that breaks the airbox would just suck hot air, I have seen people put cones into modified closed boxes, I wonder how that set up is?

The Evolution Motorsports high flow air intake for the 986 boxster is an excellent bang for the buck. It utilizes a cone shaped air filter and a revised snorkel, along with a dedicated air box. It gives a little bit of a bump in hp and creates an awesome sound !
