I actually never liked that cut scene to be honest. I know we get excited because it's new to us and all that jazz, but I understood why it wasn't used. The scene kills all mystery of the green blade. Before the prequels the reveal of that green blade was an awesome moment for me. At the time it symbolized the new age of the Jedi. Using the scene would kill that moment and build up. I don't need it spelled out to me that Luke built the lightsaber.

It wouldn't kill the mystery at all. It would just place the reveal at a different point in the film. There is no build up to that moment as the audience has no idea it's even coming. It would still have the same effect.
