Can you use an old cartilage piercing with a industrial?

It sounds like a pretty awful idea... Unless your old piercing just so happens to be magically in the perfect location and at the perfect required angle. Tthe two holes for an industrial have to be PLANNED FOR CAREFULLY and, thus, are generally done at the same time and with an industrial in mind. You can't just play connect the dots with any two piercing holes, or force one existing hole to work with a new one.
