That sounds awesome if that can be done. I would look into getting stronger connecting rods, maybe ceramic plating and such first so the engine can handle the extra stress and internal temperatures. Probably more you would have to do to maintain reliability. My understanding of twin turbos is one turbo works harder at lower RPMs and the other kicks in with brute force at higher RPM. Turbo lag becomes a thing of the past and dyno readings blow minds. I am kind of thinking of cars like the Supra TT, 300ZX TT or the Skyline R34 GTR, but these are all inline motors with mean turbos put on too. Often resulting in 600+ hp when pushed hard. That would be the coolest Volvo ever with TT
As far as the trim problem my 850 is a '96 as well and the trim is still perfect. I regularly put on the tire black on the trim to keep it kinda wet and new looking. I find it works better than all those plastic/vinyl cleaners and is cheap and easy. My door handles are fairly sun faded and this little procedure makes them look good agian and seems to prevent further fading as far as I can tell.
