Stands My grid stand question

I currently have a 2X5 with a grid base. I have grids across the bottom of the cage for stability. I'm wondering, can I take out some of the cross grids? Like, right now there is four spaces under the cage. Can I take it out and make it into like three spaces by removing two of the cross grids? I wanted to make a loft, but don't have the money for another box of grids right now! Would this be acceptable? Or would it cause my cage to become unsturdy? Here is a better idea of the cage right now!
