Nah, its a legitimate question to those who don't know better. I asked the same question to an ENT resident I work with. Besides all the other issues, as DeafDoc mentioned theres no way.to attach nerves to other nerves, or the hair cells. When you look at a picture of the auditory nerve, you'll realize why they cll it "spiral ganglion" 
Otherwise you would see alot of people getting new arms and legs who've lost those in accidents.
