You can get a smaller drake, size won't matter. If you got at Indian Runner, you would be amazed at how much less food they eat, and how much less room they occupy
I would actualy hesitate to get a female duck, knowing he is an Aylesbury. He could hurt a smaller duck if he tried to mate with her, it is best to match mating pairs by size.
Here are my two drakes, best buddies!
