Is it possible to adapt a device driver such that it works with a very similar other device?

I am hoping to find a way to adapt a scanner driver such that it works with a very similar scanner. The scanner I own is the CanoScan 8000F , but unfortunately the driver is only available for PowerPC. As I'm on Mountain Lion, this means that I can't use it. However, similar scanners from the same manufacturer do have drivers that work on Mountain Lion. Is it possible to adapt these drivers somehow such that they work with the CanoScan 8000F?
