When I designed our pickup ring system, I did it so the route could be as small as possible, thereby making the pickup ring smaller. The key to our design is the beveled corners. It allows us to move the mounting screws in closer to the pickup and hence make a slimmer, less gawky looking pickup ring. Look on our website at the way the corners of the our routing template are beveled. And yes, if you route the guitar using our template and mounting rings, they will fit nicely over the standard size humbucker route.
