89 Formula Upgrade Idea (Newbie) thoughts? Is it Possible?

Hey all, so got a 305 (LB9) formula stock all round.
Probably really common story I had 350 jealousy (LT1) and
(LB9 0-60 7.5 1/4 15.9, LT1 0-60 6.5 1/4 15.4)
Even though the 4th gens have a V8 LS1 (way better)
I just felt i was missing out on my gens best.
Then I found out about the TTA (Turbo Trans AM)
and its 0-60 in 5.0! with that Buick V6 and a turbo on top
After thinking about it I realized the potential this car has with power.
Unfortunately I wasnt the only who thought of putting a turbo on the 350
gauges in the hood scoop (damn!)
I now know of the ultra rare Carroll VHO Formula 350 (4 made)
With 0-60 in 4.3, 1/4 in 13.4!
(you vets probably already knew)
But I think since its 2012 its possible to be out done
And the reason I want to do it with the 350 LT1 and not a LS1
is because it seems more genuine to me!
So a LT1 with LT4 heads and intake
The intake isnt produced anymore but you can find aftermarkets who will manufacture on demand reasonably priced.
And a more modern Tubro that can produce more than the 5-6 psi Carroll
Then, take it further than Carroll did and replace the hood, fenders, bumpers door panels, seats, carpets dash and dash parts and if you have them T-tops with the lighter aftermarket alternative. If there are any other things you can get lighter please enlighten me. Combine that with modern exhaust suspension and differential and a t5 tranny and now what I think would be the finisher - a twin screw supercharger! (which also improves gas mileage correct?) Im not a mechanic by any means (yet anyway) so if that isnt possible please again enlighten me
I think it would have 0-60s below 4.0! And 1/4s of low 11s!

Thoughts? Please I am seriously about to get started on this as I am close to fully restoring my car and want to begin modifying!
Possible? Worthwhile? As fast as I think? Expensive?
And what are thoughts of how much its worth would be
changing from "Matching numbers"!
