Depending how the body is routed, you could try my favourite, Crawler bridge and 2 calibrated P-90's. You will need to cut the pickguard, but the sound is well worth it. The P-90's will get rid of the thin single coil sound! I also have the Nailbomb/Trilogy/Triolgy, but will be installing it this weekend so I can't tell you the sound (other than I already know it will be great - all the other pickups I have are!).
Another option is a Warpig in the neck for the death metal sounds, the hottest strat pickips are the Sinners, but I haven't had chance to hear these yet.
Of course, as always the man to ask is Tim. The one thing I can tell you is that whatever pickups you get, you will love the sound.
