Reduce fan voltage without power loss?

Here is what I was thinking:
Instead of using resistors to drop the 12V line to 7V, replace the ground line with the 5v line. That will give you a voltage difference of 7V (12v - 5V) without any power loss.
Does this sound like a good idea? Or is there a problem with doing this?
