Hmmmm, may pick up a few pickups, then: Emerald, Abraxas, Nailbomb and Rebel Yell or Holy Diver. However, from the description on their website, the Nailbomb sounds like it will be too dark. The Holy Diver seems like it's a Rebel Yell, with less treble (which I may like). And the Black Dog is an overwound version of those two.
The Nailbomb isn't a dark pickup by any means it just sounds huge (the "eq" chart on the website isn't the greatest indication of the actual sound) because of the bass frequency representation and mid spread. It has a great midrange response when overdriven and absolutely sweet when clean. It has a really wide even frequency response and is probably the most versatile and well rounded high output pickup they make. Works well with picking dynamics and vol/tone control manipulation.
The RY is like the NB with respect to base tone and response it just has a slightly backed off bass response so it isn't as huge and it has a "snarl" to it (more tone buzz words

) because of the upper mid emphasis. It isn't as hot as the NB but has plenty of drive and output and is really sweet clean and coil split.
For the grungier stuff/Muse/Tool influence and sound you are looking for I would go for the NB. I know before going the P90 route Matt Bellamy was using the NB in the bridge position.
For reference I had these pickups in identical PRS CU24s going into either a Diezel Herbert or an Axe-Fx II
