I agree with your statement - you probably should've started with a calais haha.
I can see what you want out of this car (to build something to your exact liking as you have envisioned it), however I think you'll find a lot of people on here will have mixed emotions on it. As most of the forum members are enthusiasts, they respect and appreciate the design of what was HSV's most aesthetically pleasing range. In my opinion, the clubbie is already a blinged up version of the very humble VX SS'. There are a lot of VX clubbies getting around with wheels and lowering that look fantastic! But you're obviously after more than that.
However, I rekon if you love it and that's what you want from this car, don't listen to anyone and mod it as you please! It's your car
Btw, I had a look at your VZ Clubsport, shame you didn't hold onto that one, it was beautiful!
