I might go about it a different way. I want to show that only Green Lightning will see her as Blaze, but everyone else will see missus. Since she was created with magic, she can use it in limited applications. She doesn't know about Blaze, the spell she casts will let the person she casts it on see her as the one he loves, so....

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
