Who knows? But as long as there’s a dev doing everything he/she can to do the least amount of work possible on the worgen - when not disrespecting us - we can dream to have what we want.
By the way, i found by chance an art of a dracthyr worgen as a visage form:

Too bad that we can’t chose to be worgen as a visage form isn’t it?
