changing templates help

[Cethernd]

In the Draconomicon, the prestige class Disciple of Ashardalon gives you 'fiendish perfection' at it's 12th level, which makes you a half-fiend/outsider.
If I were to make a half-dragon disciple of ashardalon, would this change replace the half-dragon template (as if you were half-fiend from the start) or add onto the half-dragon temple?

Without looking at the wording, I'd assume the intent is to stack it on. Most templates don't remove previous templates when applied.

as long as you can qualify for the template, you can add it. I know its not exactly what you were asking, but as an example, there's nothing preventing you from making a half-dragon/half-fiend/goblin as a monster, so it wouldn't prevent you from taking a class and gaining a template. Just like you could take a half-fiendish Elf and becoming a dragon disciple, which at the end you gain the half-dragon template, there's nothing preventing a half-dragon from gaining the half-fiendish template because of a PrC.

Template stacking can be done almost indefinitely and has yielded hilarious results in the past (i.e., a half-dragon half-fiend half-centaur dwarf is not really recognizable as a dwarf.)
