If money isn’t an issue for you, why not buy a ZR1 ?

Well shoot. I really enjoy taking a really good piece of machinery and making it better. Personalizing it to fit me. I know I've spent way too much money over the years on my "habit'. Wouldn't have it any other way. Don't regret one penny spent. Wife even enjoys my idiocy. When she sees a hood open, she says she doesn't even want to ask. Life's short. When you're creeping up on 70, the end of the ride is closer than the beginning. Have fun. You're only here for a moment.

I may be biased, but honestly this is probably the best option.
While I loved my '13 GS with the A&A, the ZR1 is at another level. My GS had mag ride (like the ZR1), 19/20 ZR1 wheels/tires and the same HP as a buddies ZR1 that I got to drive several times for comparison, and the ZR1 is still better. Don't get me wrong, you'll love an LS3 C6 with A&A kit, but the ZR1 is well worth the money and would avoid all CARB issues in CA.

LS3s love boost and are very reliable at moderate levels (what you'll get with the A&A CARB legal kit). Heck, I put 30K+ miles on my '13 GS pushing 15psi and it was still going strong when I sold it. And that was with a lot of hard pulls, 1/2 mile and 1 mile events.
That's perfectly fine. I have a good friend that did an A&A right after I did on his ~75K mile '10 GS, running significantly more boost than the base A&A kit and again lots of hard use (1/4 mile, 1/2 mile and street pulls), and it was still running great when he sold it 4-5 years later.

700whp is pretty easy on the LS3 w/A&A, I was just shy of it on my GS. Running the little Si trim blower with the 3.6" pulley, dual nozzle Alkycontrol methanol injection kit (running 100% meth) and Z06 exhaust manifolds and h-pipe with stock NPP mufflers put me at 672whp. If you do the Ti trim, you shouldn't have any problem breaking 700whp.

No supercharger kit that makes 700 rwhp is CARB approved. Plain and simple. You can add a smaller pulley and a tune to get you there. Any of that makes the rig not CARB legal. I would imagine having a meth kit isn't legal either. 100% sure that adding a tune to take advantage of the meth isn't legal. If you want a completely legal 700 hp Vette, you need to move to another state.

It sounds like some A&A kit-equipped cars were being flunked for modified software during the roll-out of the CVN check, but now the BAR's act is more together and they're passing.

My recipe for 700 at the wheels would include a Magnuson Heartbeat, mild blower cam, 81mm blower pulley, Z06 exhaust, and a flex fuel setup. At inspection time, you'd have to burn off all of the E85, fill tank back to unleaded premium, change the tune back to the one Magnuson supplied, and change the blower pulley back to stock. I can change a Magnuson pulley in a matter of seconds.
Nothing wrong with the A&A kit. On a street Vette, I just prefer the instant full boost that the Magnuson Heartbeat offers at just past idle rpm.

It sounds like you have a narrow body C6, You will be fine with a stock Heartbeat or E-Force, AA. You only have so much tire out back. I have 345/30/19 R888R on the back with less than 600hp at the wheels and it's a handfull.
