I could see the show having a spin off very easily. You can take one of the more popular characters and have him go into a speciality field or private practice. Or you take a relatively well known actor have him come in as a student for several episodes then you spin off with his character into another show following his career.
They do that all the time. That is how they started Melrose Place - a couple of the characters where on 90210 for a few episodes, then the new show started and it was a hit.
