I don't see the point of this question, and I don't think any of you above me do either. It wouldn't have made any difference if Beren had not died, because he came back. If Beren had not died and Luthien not willed herself to die, then Beren and Luthian would have moved away to the same part of the world that they moved to anyway, and then beren would grow old and die just like he did anyway, and Luthien would have willed herself to die just like she did the first time anyway.

Speculation is all fine and dandy, but this is one point where it just doesn't make any difference.

Also, Beren didn't die when he got the Silmaril from Morgoth. He made it through that bit just fine.
