I was thinking along those lines. I was thinking the best way to limit half-elves (and half-dwarves) was to make the feat a "racial" feat only. Like the ones from Forgotten Realms, or essentially any non-combat, non-magic feat. This would make them about as poweful as a first level human.
Consider that a first level human gets 4 bonus skill points and the half-elf only gets 3 racial bonus skill points. By 3rd level the human could have gotten the exact same skills at cross-class costs (or twice the bonus if they are all class skills, like a rogue). All other skill points (up to 17 more) are gravy for humans.
I dont think blood or languages will significantly alter the "power" of a race, and add in some general anti-sentiment towards half or bastard races (ala Dragonlance) and you have lots of reasons someone would rather be a human.
