It would be great to see something so ambitious go ahead, but I don't think there's any chance of it happening. Is it really worth the trouble and risk for a flyby?
Man first landed on the moon long before my time, and I'd love to see humans top that in my lifetime, or even just to do it again. I know it's much more practical to just send a robot, and we learn just as much (if not more) from it, but it's just not as inspiring to witness. Given the technology they achieved it with back in the 60s/70s, you'd think it should be a piece of cake to fly to the moon and back in 2013.
