Since weight variations among the same model are common and often very noticable, I wouldn't assume that the one I picked up and found light would be the same as another. Just be sure you are getting what you want.
A couple of things - you don't have to change out the pot, just get rid of the extra cap and resister, then either solder the .1 cap back in, in standard P Bass wiring config, or substitute another cap if you're looking for a brighter, more current sound... Also, I doubt that Fender made a whole new pup for this series - odds are, it's the same pups as on the MIM series, like they did with the Highway One series - although that's just a guess...
If I were the OP, I'd get rid of the greasebucket crap, then try it out before buying another set of pups - it might sound great just like that...
