Hi,
I usually get mine from addiction-fx. If you go the alnico 5 route, the pickup will be similar sounding to PAF Pro. A2 in evo neck will thin out the bottom end and add even more mids and smooth the highs, which is probably the closest you are looking for.
As DarthPhineas suggested, though, mags are cheap and you can get couple of them and try them out, maybe you'll end up liking completely other one at the end.
