I suspect that, had Maeglin's plan succeeded, both he and Idril would have ended up in the exact same way, sooner or later. The doom of the Noldor would have seen to that, just as Phary's own greed had doomed Numenor and Miriel herself.

In a way, Tuor's actions had spared them from such a fate, even if one of them had to become a sacrifice to save them both.
