Interesting point! In that respect Ghost In the Shell and the protagonist moving beyond the human body seems like an alternative take on this issue. More broadly, it looks to me like the ones who succeed in going beyond their allocated life-time are rarely at the center of the story, and more assisting figures or legends. The witch who've lived for 500 years stays in a remote forest far from the world, will help the heroes in a Deus Ex Machina way and get back in the background once her part is done.
