Hey Jason --
The reply is my (our, I'm sure) pleasure! I hope it helps!
One thing to think about also (for the sake of argument, I'll pretend like you haven't thought about it already): It appears that there are body kits that "add" a lot of junk to a car, and then there are those that "claen up" the appearance of some cars. As long as you are designing REPLACEMENT (as opposed to add-on ground effect-style pieces), you really have the freedom to do what you want with the lines of the car -- and so you just might want to make some subtle changes to the C5 (that people might really appreciate).
Sometime last year there was a VW GTI (a modern one) that a tuner had done. It still looked like a VW GTI, but WOW was this thing clean and sweet! Instead of adding to the body with flamboyant pieces, they made subtle changes in lower body lines (for instance, they tucked the rear facia under so that it looked almost like a Porsche (924, was it?)), flared the fenders slightly, etc. It was really beautiful.
On my Jeep Wrangler, there are aftermarket wide flares (to cover wide tires) available from a number of manufacturers. The ones I went with are ones that look just like the stock ones (in overall shape, and in simplicity) -- only they're wider. There are others that are jsut as wide, but that have lines, and rakes, and curves and whatnot. Now, some people like them, I suppose, but I just wanted something that was stock-like, only wider. Same kind of thinking might apply with a lot of C5 owners, you know?
Now, granted, the C5 flowing design is already good (and wide, and low), so it's probably a bit tough to reshape. But then again, the whole car might not need any tinkering. For me, I'd have prefered the C5 to have a lower air-splitter style front end -- but I WOULDN"T want to lower the ground effects of the rest of the car. Maybe you could concentrate on a couple "areas' of the care that you think might need addressing, rather than looking at a "total kit" for the car.
Finally (I'm going to get off my soapbox really soon!), whereas I think your designs are cool, I think the demographics involved with C5 owners might be the real stumbling black here. The car is expensive, the owners tend to be older (I'm only 30, though), the people who buy them may have "always liked Corvettes" (and so they might not want to mess with the shape at all), blah blah blah. I'm just thinking that the C5 might fall into a quirky demoraphic that might not have anything to do with your designs being good or bad overall.
Keep up the interest, Jason! (Sorry for RAMBLING, everyone!)
