Going to be hard to work a great Jerry tone from a two pickup guitar, that is a Jerry tone from between '74 and '77. However, it can be done. You would have to stay with either the neck pickup on its own, or the bridge pickup on its own as that middle setting, which makes a Les Paul sound like a Les Paul, is not a tone associated with Jerry. Bob, yes, Jerry no. So you would be working the neck pickup for the hollow, bell tone, and the bridge pickup for the trebly punchier stuff. With the right pickups, you can achieve some Jerryness.
I am big fan of Seymour Duncans. Pearly Gates are great pickups, lots of treble I think which is what you are looking for. Another interesting pickup they have now are the P Rails, which are humbuckers that can be used three ways with a three way switch. POsition 1 gives you teh humbucker, position 2 would give you a true P-90 sound which I hear is pretty accurate to a real one, and the third position is a single coil (rail).
IMO, the P-90 is a great pickup for getting that bell tone of the Travis Bean, in particular the '76 sound. Very big, shimmery and bouncy. The downside of these pickups are the aesthetics. The look a little different than your traditional bucker, then again you might be able to put a cover over them. I think it is an interesting thing to have a versatile pickup like this, especially since you would be only using two of the three positions on the guitar (Neck only or Bridge only), as that middle sound isn't really Jerryesque. Mike Bloomfield yes, Dicky Betts, yes, Jerry no.
Properly modded with three way toggles I think this could be a dangerous sounding guitar. Then again, I could be completely wrong. There are other cats here who know way more about the gear stuff than I do. Keep us posted.
There are only two mantras. Yum and yuk. Mine's yum.
