as far as I know, the bridge and neck versions of the BK pickups are different- if you have a black dog neck pickup, putting it in the bridge won't mean that you have a black dog bridge pickup- it'll mean that you have the black dog neck version, just in the bridge position.
If you're handy at soldering, you may as well try it, of course. Just I'm guessing that there's a pretty reasonable chance that you'll want to put it back the way it was when you're done...
