Antipaladin's Aura of Cowardice and the Dread's Aura of Fear Stacking?

[Echoen]

Aura of Cowardice (Su)

At 3rd level, an antipaladin radiates a palpably daunting aura that causes all enemies within 10 feet to take a –4 penalty on saving throws against fear effects. Creatures that are normally immune to fear lose that immunity while within 10 feet of an antipaladin with this ability. This ability functions only while the antipaladin remains conscious, not if he is unconscious or dead.

Aura of Fear (Su)

At 3rd level, a dread radiates a palpably daunting aura that causes all enemies within 10 feet to take a –4 penalty on saving throws against fear effects. Creatures that are normally immune to fear lose that immunity while within 10 feet of a dread with this ability. This ability functions only while the dread remains conscious, not if she is unconscious or dead.

As you can see, they are exactly the same ability. However, the bonuses are untyped, and they have different names. So can a Dread 3 / Antipaladin 3 provide a -8 penalty on saves vs fear?

Well you are giving up quite a bit for an admittedly neat trick.

RAW yes, as two abilities with two different names will stack.

Similar things happened in 3.5 when UE had evil paladin variants who's divine grace stacked with the blackguard's dark blessing for the same reason.

Things really got screwy when the same character dipped a few levels of Hexblade.
