Could i just change her to some sort of chemical mage then.

As in poison gas's and stuff, but still healing.

So for example if i went chemical mage. Moonlight gas would be a strong spell that causes mass hallucination and is known for its near translucency besides having a shine to it. This is high level not by it's strength but the quantity released. 

Just thematic spells like that.That are more about the charater.

EDIT
By mass i mean the areas large enough to make a large crowd hallucinate.
