I believe it was in the poll, and it was actually a contender for the top 3. There is a possibility of something like a half-Elezen being added in as a new Hyur clan in a later patch/expansion which would be cool. I highly doubt though that it will get it's own race slot since it's just a Hyur with modified ears. I don't think any other mixes of races will get it though since there's no precedent currently in the game for it, but who knows?
