Well, actually the paladin's ability is called "Aura of Good" (for obvious reasons) but I see where you're coming from. Sure, Chaotic Aura sounds fine.
Edit: Decided against "Chaotic Aura" because I already had "Lesser Chaotic Smite" and "Chaotic Smite", so it sounded repetitive. Instead, I changed it to Aura of the Chaotic Champion, which I think sounds much better.
