id use a 59n over the 59b, the 59b is a little higher output which will make it harder to balance outputwise and darker which will give an even more drastic tonal change than what is already going to be a significant difference. broadcaster bridge and 59n would be a better match. the seth or antiquity are good suggestions too, but get the neck versions for the same reason as i mentioned earlier. the pup lew mentions is a great pup for sure, love mine!, but it comes with a custom shop price. they are usually tapped which means you can use a 5 way switch and get:
1- tapped bridge
2- tapped bridge + neck
3- neck
4- full bridge + neck
5- full bridge
if you used a push/pull pot you could split the neck pup or put it in parallel
