Sounds like a great project, but I'm not sure you could achieve maximum performance and/or smoothness, see the attached slide from the 8L90 intro course.
Not being an expert I can't tell how much of this is overcaution vs reality, but unless you can tune the TCM or have an experienced tuner to help you out, it's kinda risky. If you only change clutch packs and absolutely nothing else, this might not apply, but I'd think line pressures etc. will still have to be calibrated and stock values may not work well...
