Hmmm....interesting idea. I think I prefer the original, though. Across the Stars seems a bit to....heavy, if you know what I mean - it doesn't have the Elvish feel that Aniron has. Try putting Duel of the Fates in the part of FOTR where Arwen is being chased by the Nazgul. I thought it went fairly well - the singing added a sort of viciousness, and the parts without the singing had a "running away" sort of feel. Also, try putting "The Legend Spreads" from Braveheart in during the part where the signal fires are being lit in ROTK - it's perfect! I've also been trying to see if I can put "Hedwig's Theme" from Harry Potter in there somewhere, but I'm not exactly sure where it should go. Merry Christmas, by the way!
