How would you people feel about a familiar character returning in another's body? Or an old character in a new one's body, or vice versa?

There's this idea I've suggested a few times, of Shao Kahn returning in Liu Kang's body, while Liu Kang's own soul is either still in there and trapped, or in the netherrealm along with the other dead heroes.

Shao Kahn could manage to fool everyone into thinking he's Liu Kang for many years. Maybe he could fool Raiden for the next 25 years, despite acting oddly.

One of "Liu Kahn's" variants would see him fight like he did in the past games. This is the variant he'd use in the story mode when pretending to be Liu. Another variant would be reminiscent of Shao Kahn's own gameplay, where he creates a fire lance and kneel in order to throw it, or hit people with a fiery hammer. This is the variant he'd fight with once his secret is out in the story mode.

Another possibility for a body-swapping storyline is the mysterious woman in Jade's MK9 ending, resurrecting and healing Jade's body in order to take it over, while Jade's soul is still in the netherrealm.

I do realize it's been done with Onaga already, but Reptile's body was altered so drastically it might as well have been Onaga's to begin with. Not to mention, it barely mattered that it was Reptile's body that was taken over. I'm talking about a much more subtle kind of body-swapping, where the original's body is perfectly recognizable, and you don't even know until later that someone else is inhabiting it.
