Now that is a truly epic way to end a pretty freaking epic battle! I love this! But wait...maia?! LMAO!!! That's right, the Peredhil were all given the choice of which kindred with which they would be counted and no specifics were mentioned, at least that I recall, so that should work. And now that you mention it, I'm surprised none of Luthien's descendants chose that, since they are descended from Melian through her. I'm looking forward to reading what you've got planned on this new twist, especially about this having been Lúthien's choice in this 'verse.

Just one thing: what did Morgoth implant in Buffy's mind when he grabbed her by the throat? I have a very bad feeling about that...
