Just about any pickguard maker can do it. I used Jeanie, Roger used to make my guards but now I make my own. Keep in mind you'll have to route the body for the humbucker position change. My only suggestion is measure any guitar with a humbucker, that you like. Humbucker to close to the bridge will be trebley, to far from the bridge will add bass. If you don't specify where you want that humbucker, they'll stick it anywhere they want. Good luck with it, at least now your humbucker pole pieces will line up with the strings 😛
