More or less. Can't say I've ever seen lightning used in either the anime series or mentioned in the light novels, so I have no idea what the possibility for it is. Sometimes I think that Lightning is more associated with wind then fire, or possibly even water if you want to associate lightning with clouds. But I'm not denying it either, so let's just say that once you get to that point IC, I will decide if it's doable or not.
