I've had the idea of using a standard Tele pickguard as a "guide", mounted to an Esquire pickguard, to use as a Dremel router guide to route out just the bottom ply, on a 3-ply pickguard, to make a channel, or "pocket", so to speak, for the Secret Agent to lie in. Maybe held in with some RTV, or maybe some of that credit card "booger" glue. So far, it's just an idea in my head. I haven't tried it yet.
