Project Q has a skeletal ogre, skeletal hill giant, skeletal musicians, a skeletal dragon, skeletal horses, some human zombie variants, a female lich, and a green zombie dragon.
I have some skeletons in the works for bugbears and gnolls - the only piece I'm missing is a good canine skull to use as the base (might have to make it myself). I also have a zombie frost giant in the works.
I agree with Tarot, this would make an excellent theme for the CC Challenge.
