The key to using multiple wheels on the same bike is matching the "freewheel position offeset" on all the wheels. That's the distance from the inside dropout face to the high gear sprocket. These usually vary slightly between brands, and can throw off indexing if not matched.

Matching is achieved using a shim behind the cassette to bring it out to the needed offset from the axle face. I've done this with most of my personal rear wheels, and BITD when working with race teams, matched 100% of the wheels used, both on bikes and spares. This ensured that any wheel swapped out in a race would be compatible with the bike.

To do this, you'll need an assortment of shims and a depth gauge to measure the step from axle face to sprocket.
