I've never seen it done in a relay, but couldn't you have a "butterfly" arrangement (e.g. some teams run ... 1 - 2 -3 - 1 - 4 - 5 - 1 ... and some run ... 1 - 4 - 5 - 1 - 2 - 3 - 1 ... though I'm sure it could be more complicated than this). Having a control that's visited more than once could add to the excitement, especially if it was a spectator control.
