Taunt says:
You can demoralize opponents using Bluff rather than Intimidate (see the Intimidate skill description for details) and take no skill check penalty for being smaller than your target.
Cornugon Smash says:
When you damage an opponent with a Power Attack, you may make an immediate Intimidate check as a free action to attempt to demoralize your opponent.
When you use Cornugon Smash, can you use the Taunt feat to make the demoralize check using Bluff?
