Yeah, I like changing and trying out tires too! I have two sets of 26" wheels for my current commuter, which is my primary ride. One always has smooth 2.0 road tires and the other has studded tires in Winter and off-road tires otherwise, so I can swap the wheels at a moment's notice. Beats changing the tires once get over the additional expense (wheels, cassette, disk rotors). I'm thinking about getting a third set and keep narrow tires on it for longer road rides with a club, but now my BD build is the top priority.
