If you don't mind the look of the 4-drawer fronts on you sink cabinet, and your plumbing is positioned out of the way enough, you might be able to use a full depth drawer on the bottom and a shallow depth drawer in the middle (I almost did this myself, but DH claims I'm addicted to drawers, and we should maybe have just one "normal" cabinet... bah!)
Anyway... They don't make a shallow depth, 36" drawer either, but you can make one out of a 36" wide deep drawer and one of the shallow drawers. You have to cut the bottom piece of wood, but otherwise it's a pretty straight forward parts swap...
I actually did it, to make a shallow depth buffet...
