well, i just finished a very high end acoustic album with some world class players, and quite frankly , the last thing i'd wanna do is add protools plugins to it. i use external reverbs like the digital EMT or the TC6000. we then summed it into an analogg rupert neve with manley final compression. maybe the TC stuff for final limiting as a plugin, depending on dynamics, but its very expensive.....i think the mics and placement will be the best 'plug ins' money can buy....i think there is a lexicon 480l simulation out there for around 400 bucks, maybe its a real winner i don't know... good luck, it certainly is a lot of fun working with these high sample rate machines and analog combination...
