AC, that just sounds like a standard Aura attack. Think of what Glynda id in the first episode - she basically did a magic missile using her aura alone. Your proposed semblance sounds very similar to what she did,  and therefore would come under 'Advanced Aura Techniques' rather than a semblance, which is individual to the person.
