I quite agree that no sizable number of Black Numenoreans remains, and I also agree that no, their kind is not likely to have any sort of resurgence, ever. But do recall, that is only an opinion, and that if Mevans were to want it, the loophole for adding Black Numenoreans is there.

However, Aragorn's lengthy life isn't entire the fault of his Numenorean blood. The Numenoreans were gifted with great life, but the line of the King of Numenor is the human side of the lines of the Halfelven. Elrond's brother, Elros, was also Half-elven, chose the life of a Man, and lead those among the Edain who had helped the Elves in their fight against Morgoth to Westernesse/Numenor. The rest of the Edain were granted great wisdom and lengthened lifespans, but none could rival the house of the Kings (and Queens) of Numenor. Elros Tar-Minyatur himself would live to be some 500+ years old.

However, the fact that Aragorn is only a distant descendant of Elros, while Elrond is the brother of the first King, means that, in case you hadn't considered it before...

Elrond is the rightful King of the West.
