Depends how you do it. You could do an "opposite corner omnis" 4WD, which has been done before--say you have an omni on your left front corner, you put another on your right rear corner. It has a similar effect in terms of friction reduction, but it keeps your center of rotation in the center of your robot. Now whether that's a good idea depends on your robot and the game--you might actually want to pivot elsewhere!
