If you are ready to switch her and she is in an enclosure just as big right now, you could just go ahead and do it. How she does with it, no-one knows for sure. But I don't see how it would be worse then being in a large tub.
Just be mindful of those doors on those cages. I've heard of geckos getting squshed in those door, not just in the middle, but on the sides where they swing inward. Always make sure the gecko is nowhere near the doors before opening or closing them. I agree, it would help to set it up similar to the tub, just so that it seems a bit familiar with some familiar deco.
Like Mleedee said, leave her be for a week after the move , and then continue on with handling.
That's what I would do, as well.
