Hmm I don't think Miracle Man or Painkiller would be ideal, they have a whole lot of "cut" around the highs, and you mentioned you want to avoid ear-piercing highs. I don't think any in the BKP range are as shrill as the Duncan, but it seems your best bet to go for the warmer, Alnico, pickups. Warpigs being only a "little" too dark would lead you towards the Holy Diver or Crawler. These are both high output pickups with a lot of bass and mids and less treble so you avoid ear piercing highs. The Holy Diver is quite modern with huge harmonics and singing leads, the Crawler is a vintage flavour of the same thing with a little less chunk and a bit more mid-bite. Better for blues, I'd say.
Rebel Yell and Nailbomb are also to consider, but they may have more bite than you're looking for.
