I have added a Dracolich (ancient red dragon) to the undead category. Quick comment about the dracolicch: I don't think a dragon gets stronger (or stays the same) when it becomes undead. I believe making a dragon undead makes it weaker, at least initially. Thus, my version of an ancient red dracolich is 2 CR lower than a typical ancient red. However, this doesn't mean that a dracolich can't become more powerful than a living dragon, it just takes lots of time and work/effort.
