Do you purchase music on your wife's account? If you do you don't need to make a second account. If you don't purchase music you can use her iTunes just set it to manually add music so you don't have all the music synced to your iPod. With manually set you can add her music and your own music to the library and add whatever music you want to your own iPod.
