Maybe it wouldn't make too much sense, considering the whole 'what age you look as a ghost' thing got skewed in subsequent SE releases, but even as someone who didn't care at all for the prequels, I really want to see Haden and Ewan portray their characters with actual good dialouge to boot.
The Force Awakens likely isn't going to experiment with this idea, but maybe in the next two films of the trilogy, one of the directors might toy with the idea of drawing back to themes and ideas from the prequels. Not to remind us of the dissapointment, but maybe to make up for some of their faults.
