If tim said riff raff, then you get the riff raff.
The only time I've ever sent a BK back for replacement was when I didnt take tims advice, because I was fixed on something else. I got what he advised (as usual) and it was spot on (as usual).
If its off the mark for whatever reason, then you have a familiar reference point for memmers of the forum (and tim) to advise a replacement.
The CS neck lore is as a humbucker. Its a superb pickup. Its also only one of several that I've used from BK that satisfy the smooth lead distortion requirement but I never tried to get SRV tones from anything, ever, and as philly says, split HBs are notoriously non-single-coily, in tone even though thats what they are electrically. Youre likely going to have to expect tonal compromise.
