I've been thinking strongly of going with Carvin pickups for both my Spirit GT Pro and Hohner G2T. I want to go with the covers to maintain the original look but they also sound fantastic.

Check them out and see if they will work for you. The link above is just for single coil and mini hum since you already have your 2 humbuckers.
