The problem with your argument, even if Elrond could succeed Elros, is that relation to Elros is not the reference point for kingship of the Dúnedain anymore. Elendil and his sons are, and to a lesser extent the latest king. Elessar is Isildur's Heir, not the Heir of Elros. His line has also married into that of the kings of Gondor, securing his claim. Elrond, however, is only a distant great uncle of Elendil, so he doesn't really have a legitimate claim.
