How about this idea for the Undead Dragon to be featured in the Adventure Path? (name forgotten), the one from White Plume Mountain:

CR 20
Desecrating Aura: (See Nightshade in MM, responsible for some of the unusual math above)
Energy Drain: 1 level w/ bite
Spell-Like Abilities:
At will - Contagion (DC18), Cone of Cold (DC 20), Confusion (DC 19), Deeper Darkness, Det. Magic, Gr. Dispel Magic, Haste, Hold Monster (DC 19),Invisibility, See Invisibility, Unholy Blight (DC 19)
3/Day - Finger of (DC 22), Mass Hold Monster (DC 24)
1/Day - Plane Shift
All at CL 29th.
Summon Undead: 1/day, 11-20 Shadows, 3-7 Gr. Shadows, 2-5 Dire Wraiths.
Frightful Presence: Perhaps one like the Nightwalker (paralyzing), but since that's similar to the Dracolich, perhaps an aging or corrupting presence instead such as loss of 1 level (no h.p. for dragon). DC 29. Radius 60' (+?)
Breath of Decay: 60' cone, every 1d4 rounds. Since destruction of magic/items is a Nightshade theme I'd include a disjunctive effect. Perhaps a level drain coupled w/ magic drain (but the level drain is too similar to a Shadow Dragon). So Decay, 1d4 Str/Dex/Con Drain DC 29 Fort for half. Those who fail also suffer the effects of a targeted Dispel (or Mord's Disjunction? Perhaps w/o item damage? Perhaps h.p. damage/hardness loss to all items?)
This creature is an amalgamation of Nightshade stats/stat progression/nature and the comparable Purple Worm to Nightcrawler "upgrade", but using a Red Dragon of similar HD.
It's built as an idea to work off of for those of you interested.
While it may be too powerful for when the AP dragon shows up, it IS a classic from Gygaxian times and is meant to stand out.
