Eru forbid this...

[Luthien_ Tinuviel]

Beren and Luthien can't die and come back as mortals, oh no! They're the romance of the story, so they need to become gods and solve every conflict and show up at every battle!

Exactly! Why not just cut out the Valar altogether, except maybe Manwe and Morgoth? That way Luthien can take Varda's place, power-wise, and they won't have to go to the trouble of introducing new characters! And Beren can replace Orome, maybe....

Finrod will be evil. He will actually capture Beren, and take him to Sauron's Isle, seeing as he works for Sauron and all. Then he can be killed in a warg accident, instead of fighting the werewolf to save Beren's life. Perhaps there can be a "Return of the Hyena-Lemmings".
