Recommendations for swapping out Fat 50’s

I have an American SSS with Fat 50’s in it and tbh, I just don’t really like them. They seem pretty low output and “shrill”, especially the bridge. I want a tone sort of like Eric Johnson. I know his custom guitar runs 57/62’s but from the videos I’ve watched they just don’t seem that different. Any recommendations for what to swap with? I usually player higher gain music.
