I have no experience with the Miracle Man neck. Spec wise it looks like it has loads of power which would lend itself well to soloing in the upper register of the fretboard.
Cold Sweat neck is a nice pickup, very articulate and singing, can do cleans well, too. I have one in my PRS for a few years now and still no intention to change it. In another guitar however it was too muddy on the low strings (sounded fine on the treble strings though). I replaced it with an Abraxas neck which is still in that guitar together with a Cold Sweat bridge. It has no problem keeping up in volume with the Cold Sweat bridge. So I guess Abraxas neck would also be a valid choice.
I also like the VHII neck, a bit more vintage feel, a bit more output than the Cold Sweat neck but also very articulate and singing. For cleans I may prefer the Cold Sweat.
I once got the recommendation from Tim to try the Crawler neck (because I had one) with the Miracle Man bridge as he said that would work well, too. Never got around to try that but from an output perspective I think there would not be any problem since I tried it once paired with an Alnico Nailbomb and it had no problem keeping up with that one.
So the best thing to do would be to contact the BKP team, discuss your tonal goals with them and consider their recommendation. In fact many lower output pickups work in the neck position due to the increased string movement.
