I like the GT2 the most, although I would go with a silver hood if I'm sticking with Factory look wheels and more subltle side skirting. In silver, the intake louvers that go directly below the hood breaks up the silver in a nice flowing manner.
I actually ordered that louver from DEVEK and was going to try and retrofit it to my GT3 MK1 bumper (holes lines up perfectly) but it never happened.
I've seen a Boxster with a 02-04 Standard Carrera facelift and I wasn't too impressed. I think it photographs better than it looks in person. My lady passenger on a quick glance said "I can't tell the difference". But girls always say that.
Either way you can't lose, those headlights are awesome, the best ever to grace a 911. Too bad they didn't stick those on the CaymanS and new Boxster. The Cayman would have been perfect that way, like a mini 911 with a nicer rear.
p.s.
that was an excellent photoshop, I'd love to see it done with the GT2 front end.
p.s.s.
All 911 and Boxsters on 18" wheels look 100% better with sideskirts, otherwise it looks jacked up when compared to one with aero. Makes it look lower, wider, longer, best mod I've done by far. I once had to convince several non-Porsche people that my car was a Boxster.
