I've seen this done in hand reconstructions. They can take the sural nerve that supplies sensation to the back of the lower leg, and can graft it into the hand and even cut it into further smaller pieces if multiple nerves are damaged. There's a risk of neuroma formation (painful benign tumor from disorganised nerve regrowth) with all damage nerves, whether they get repaired or not though.
