Maybe get her an identical hide to put on the warm side? I did that because my bp was staying in this one hide on the cool side and I was concerned he didn't feel as secure in the warm hide - she now rotates between them both. You could go ahead and throw in the light and just change your method of increasing humidity. I say damp towels (next to a humid hide) is the easiest/best way - less work, no more misting and you're not risking getting the substrate too wet.
