Welcome to the forums. Nice to hear of your excitement. ^^
Suggestions for Lorien are a bit tricky right now, since we haven't released them yet. But you're not suggesting anything gameplaywise, so I guess it can at least be answered.
I don't think the Light of Earendil is necessarily more fitting for a certain kind of Elf, since all Elves are enamoured with starlight (to put it very bluntly). Also Galadriel gathered the Light in her phial for Frodo, so there is a connection between her and the star.
But in the end we needed a new final Spell for Lorien, and the community gave us this great idea, so all just fell into place. ^^
