What do you think became of Luke Skywalkers hand when it landed on the bottom of Cloud City and other questions (details inside)?

My guess is that it landed on the ground next to a science colony’s researcher’s lab and cloned a new Jedi Master. Or at least it was crushed by the atmosphere.
Also If the rebellion won could Luke just get a cloned hand seeing cloning technology existed…instead of the mechanical hand that was damaged on the Jaba the Huts sail barge.

Almost finally couldn’t the cloning technology be used on Darth Vader so he doesn’t have to wear the plastic suit, and restore the force lightning….
Can the Lord of the Sith not afford limb cloning?
