LS3 Envy?

Personally for me, I just like the LS3 because it's a great engine. Not because it's newer or makes more HP (although that's always a plus). My friend has a C5, and I love that Vette too. I just love Vettes and don't care what C-version it is. Yes, earlier C's don't have the same HP, but for their time period they still had plenty of snot, back then and today (save the early ones before the small-block arrived).

The Best of Corvette for Corvette Enthusiasts
The big news for 2008 was under the hood: Engine displacement was increased to 6.2 liters (376 cubic inches) via a bore increase. Output was upped to 430 hp (424 lb.-ft. torque) and a new engine designation - LS3 - announced the good news. Credit for the increase went to revised a camshaft / valvetrain, a high flow intake and the use of the Z06's fuel injectors. A new for '08 dual mode exhaust (RPO NPP; $1195) which bypasses the muffler for a very aggressive sound. A similar system has been used on the Z06; the difference being that the Z06 used 3 inch pipes and the LS3 uses 2.5 inch pipes.
The manual transmission shifter, which already worked amazingly well, was refined via shorter shifts. Upgrades in the automatic transmission resulted in quicker shifting. Two colors, Jetstream Blue Metallic Tintcoat and Crystal Red Metallic Tintcoat were added and the Le Mans Blue Metallic and Monterey Red Metallic Tintcoat were discontinued.
There were no changes to the Z06 for 2008.

That aside I'm quite positive about modding a car. If your factory or extended warranty (if any) isn't a consideration and you want to do it...go for it! Use a quality shop and components...enjoy your car!
Long tube headers, and it gets louder, hotter inside, and it may not pass emissions.
Cold air intakes, be they front breathers or back breathers are still bottom breathers, and make you more susceptable to hydrolock.
Tunes...well you don't know what you're getting.
Get more radical than that, like going into your engine to do cams and such, and you do so at a bit more risk.
Just about any mod for power you do is liable to cost you at least a little, in drivability and/or dependability.
And finally, any "simple bolt on" mod that you can do on an LS2, can be done by an owner of an LS3 and it will respond just as good, if not better. ....So at the end of the day, you will still wind up right where you started if you are comparing "like to like".
Trade up. Anything less than trading up is a bandaid.
If you trade-up instead of modifying, the best you can ever hope for is still only a stock car. When you modify you're not constrained to a stock configuration...the sky is the limit with respect to the performance that can be achieved. A 'properly' modified car can far exceed its stock counterpart (or even the stock model you might trade-up for). That's hardly a "bandaid" in my opinion.

In the OP's case I'm not sure what he's looking for other than bragging rights but instead of taking a huge financial hit trading-in his car (for 30+ horsepower) he might be better off doing some light modifications to achieve his limited goals.

I don't necessarily agree with your "bandaid" theory. Sure, there are advantages in trading-up to a more powerful model Corvette but there's a lot to be said for modifying what you have as well. You brought-up some excellent points and I believe there are pros and cons no matter which way you go. Many factors affect one's decision whether to modify or trade-up (warranty, cost, useage, level of modifications, etc.).

Be it LS2 or LS3.
"the best you can ever hope for is still only a stock car."
Don't know if I agree with that. Some are going to mod whatever they get. But the starting points will be different.
