The most practical way would be to use a lens in a #0 or #3 shutter, and just swap the lens cells.

The old convertible Symmar lenses were optimised for 1:3, and a 135mm or 240mm Symmar would be my first choise for reversing: The 135mm is in a #0, the 240mm in a #2 shutter, both of which have the same threads on both sides. Reversing one of these will give a lens optimised for 3:1, with decent performance from 1:1 to 10:1.
