It would have to be a very altruistic society to forgo the pleasures of their own present, forward looking lives, to present some forgotten ancestor with a return to a second presence.
My argument is that each generation has sufficient interest in their parents and immediate relatives to insist that they are brought back when it becomes feasible to do so. When they are brought back they will feel the same about their parents and so on. "Some forgotten ancestor" doesn't enter the picture. Plus however difficult or onerous it may be to accomplish, given time and progress, you simply need to wait longer until it becomes feasible.
