Most likely not. Warforged aren't exactly low fantasy stuff, in that they're basically self-aware golems and fantasy robots. Your best bet would probably be just going for an elf who's variance might be the type who doesn't need as much sleep or sustenance as humans if that's what you're looking for. If you're looking for crazy natural armor and inhuman strength, maybe go orc instead. They're usually stronger than your average human, though with a lower life expectancy and more high maintenance.
