A few brief shots from the alternate opening are actually in the director's cut (and maybe the other versions too) in pristine quality. They appear right after Lily touches the unicorn intercut with her getting lectured by Jack. If someone wanted to restore the opening, they could use those shots as a reference.
By the way Sean, have you considered addressing on your site the debate over whether Legend influenced Nintendo to make The Legend of Zelda. I don't think it could have inspired the original game since they came out a year apart and aren't very similar. However, there are some interesting similarities with the '98 game Ocarina of Time.
