It would help a bit, but if you polish a turd and put nice pickups in it, it's still....wait, I guess turds don't need pickups. You get the idea though :D
Not calling your guitar a turd here, just using a metaphor. It's obvious that you're very attached to your guitar, so if you want to improve the pickups that's fine, but I would say you would be better off saving BKP's for another guitar. Go for a set from Duncan or Dimarzio.
