Nice work. I just went through similar rounds with my G5220, except I retained the stock pickups. CTS pots including a no-load tone. I put a parallel treble bleed on all three volumes and the result is really pretty cool - in the middle position I can roll of the neck volume slightly and get outrageous sparkle and clarity. It almost sounds like an mic'd acoustic. There is a lot of potential in these guitars if you're willing to put in the time and effort.
