Don't let DCR rating fools you - output level is also related to wire material and gauge, magnet type etc so trying to compare two pups solely on DCR is at best misleading. Also, the very same pup will sound way louder on the neck position because strings have a wider movement here than in bridge position. BKP necks are usually wound cooler so they don't overpower the bridge.
FWIW on my Crawlers set, the bridge is 15.4K and the neck 7.8K (but with different magnets and wire gauge), and they do balance well. Also, my SG currently have a Mule neck and an old JB(j) on bridge and balancing them is mostly a matter of height adjustment.
Now I don't (yet) have any experience with neither the NB or Abraxas so I can't tell how they'd go along, but if that's what you want, you'd better stay with the Abraxas neck and ask Tim to eventually adjust the winding so the pair matches. You'd better ask Tim before you order anyway ;)
