2nd wheelset.
However, if you want to avoid “gotchas”, match the hubs between the two. That way brake rotors will be identically spaced, as will the cassette.
Nothing like dropping in a spare wheelset and finding out the rotors are about 1-2mm different spacing, and now graze your brake pads.

There is another issue you haven't touched, the gearing change from the circumference of the smaller tire. He'd be essentially running about 5-8% slower because of the smaller tire for the same effort. Pickup will be faster but once up to speed, the rider has to pedal faster for the same speed, negating the rolling resistance and aero benefits of a smaller tire.
