Granted, you'll have an extra rim, but it could be done again if you ever trash a wheel on the road.
Or if you have a trash rim or can borrow one from an LBS with the same number of holes as your new wheel, you can make the exchange twice. Once onto the trash rim, and then back onto your new rim. Return the borrowed trash rim, and you are good to go. Sounds like double work, but there will be no chance of a screw up if you make the first exchange correctly by rotating the trash rim to the right position against the new rim. And of course you don't have to true and tension the trash intermediate wheel. It is just a place holder.
