But on to Jon... A true and unique second life by warging into a dead body would truly be something. Remind me who these bodies are... Rangers or Wildlings? But don't you think that someone would notice if a body was up and walking around again? He'd have to hightail it out of there. He'd be a loner. He'd be a former brother of the NW forced to live alone north of the wall. And he'd have warging powers to have the forest critters help him.... hmmmmm, sounds like Coldhands.
Do we really need another Coldhands?
I think the point about Jon warging into a corpse in the midst of hundreds of people who aren't particularly fond of wights is a valid one. There's no way he lasts long enough to signal a parley to explain the situation. Further, how could he plan this with anyone else? Who on the Wall would go along with a plot to essentially (in their minds) create a wight? Mel? Is she going to hold off everyone from ripping corpse-Jon to pieces the moment they see him?
Here's another thing: Assuming Ghost survives, he doesn't seem like the type of direwolf that's going to be cool with hanging out with a corpse-Jon. He's already independent enough to disappear on his own for days at a time. What would keep Ghost attached to corpse-Jon? And if Ghost leaves then Jon symbolically ceases to be a Stark.
If Ghost dies, it's the same situation; Jon symbolically loses his Stark status (the same thing that happened to Sansa). Then again, perhaps GRRM *wants* that to happen so that can be Azor Ahai reborn instead.
