Ask BKP. They do slanted pickups but not to suit all guitars. I know that they can't do the Schecter Reaper multiscale, for example.
I guess there are several pickups that will do what you want. Black Dog, Emerald, Rebel Yell, Cold Sweat, Impulse, Aftermath, Painkiller ... it depends really on the characteristics of your guitar and the exact tone you are going for.
