Since you have an SG and mentioned AC/DC, I would think that Riff Raffs could well be the way to go. 8) And it's not like RRs are that hot, and all the BKPs are quality pups that turn out decent cleans for what they are. (Let's not forget that French jazz player who uses Warpigs! :))
Still, since the subject of mixin'n'matchin' was brought up, what about a RR in the bridge and SM in the neck?
