I more or less agree with the silverwheel's statement.

But to play the devil's advocate:

(I'm only speaking through In Lucas's mind here...) The young ghost means that you look like when the "good" person in you died. BUT, we know Vader came "back from the dark side" at the end of the movie (hence the "return" of the title). So... does this means that the old dying Vader was a good man at the end of his life? I would say: yes and no. Yes, he brought "balance to the force" by "balancing" Palpy into the depth of the Death Star... but does this redeem a life of doing terrible things? No. So if we keep the "Lucas point of view" about Jedi's ghots, then it makes sens to have Hayden at the end of the movie, because Vader can't be redeem by one good move at the end of his life.

Of course that's a more cynical way to view things than the OUT, where it is implied that Vader, even with a life of being a "galactic vilain" could be redeemed by one good move. (something that I now find a bit odd, but that's just me).

It's a matter of point of view here. Both can be understandable to me. BUT what is not is seeing Hayden at the end of ROTJ if you did not see the prequels. Hence my question about the acknowledgment of the PT by this fanedit or not.

PS: hope I was clear, english is not my first language and this was a bit difficult to put out, lol...
