I think something "elflike" in the High Men sense is inevitable once you have human modification guided by human desires. Tall smart pretty and long-lived? Yeah. Even if they're not superhuman, just a selective concentration of the human gene pool, you'll get the same effect, though explicitly *not* living longer than 120 (because it's Hard[1]) would cut off one big elf-like feature.
[1] Though I'm not sure how plausible that is given people who know what they're doing. Longer life should just be a matter of spending enough energy on sufficient maintenance, uncapped by evolutionary pressures like disease predation or violence.
