At this time, we do not make slanted multiscale pickups with pole screws and studs in passive mount, for 6 string, 7 string or 8 string guitars, even as Custom Shop builds.
If your slanted multiscale guitar has a soapbar type housing--we call this "active mount"-- we may have a stock model or be able to make a custom shop model. Please contact customshop@seymourduncan.com with the measurements of your stock pickup, the model of your guitar, and the tone that you desire, and we can get back to you whether we can build that for you.
