A lot of people have trouble with queen excluders. I don't use them and I don't recommend them. However, the most successful way of employing them is to confine the queen and brood to one ten frame box, put the excluder over it, and super above that. This is how the bee lab at Guelph runs their colonies, how most commercial beekeepers I know run their colonies (if they use excluders. It used to be the standard was two deeps for brood and then an excluder. The hive would often get too much honey in the brood area. If you used deep supers, you could always pull frames out of the brood nest and move them into the supers, but it's simply a lot easier to run one story for brood and then the honey all goes into the supers. In the fall, the excluder can be pulled and the hive wintered as two stories (the second being full of honey) or as they do at Guelph: winter as a single.
