(Spoilers Extended) Jon's plan isn't going to work because it's failed before.
Back in season one Allister Thorne was sent to King's Landing with the hand of one of the wights that attacked Jeor Mormont. This happened in the books as well. Tyrion made Thorne wait upon arrival, causing the wight's hand to decompose to nothing but bone.
Jon's plan is to do the exact same thing, but with an entire skeleton. I can't imagine him getting it to King's Landing any faster than Thorne did and Throne didn't have to bring more than a hand from all the way north of The Wall. Maybe Jon will teleport around the world like he's been doing recently?

The wight would be 'alive', wouldn't that make the difference? Only the hand decomposed, maybe the entire thing survives
Pretty sure the hand was still moving. I don't remember if it was or not but if it wasn't why would they even send it in the first place. Just a severed hand at that point.
