Yea sure why not.
I feel like in about 100 years they'll add an interracial check box to those applications where they ask you what your grade is.
I'm hispanic, my girlfriend who I plan on marrying is white. What if our child marries an asian? And their child marries a black person? And then their child marries somebody middle eastern?
I see interracial relationships all the time and I think that with kids who have such diverse backgrounds as that, it will be difficult to place many people in a particular race group.
