Don't forget the ride camera for the finale. I don't even remember the last time that worked properly.
Be careful asking for a new script. Every time SSE's script has been changed in it's 40-year history they've watered it down. 2007 refurb was the worst but in this day and age they'd probably throw the entire thing out and start over.
As for narrators/music, we need something really emotional ('94 ascent music but through the whole ride) with a narrator similar to Jeremy Irons. People who come to mind are Morgan Freeman and Benedict Cumberbatch. I feel that's the best way to go.
