That thing might work. Depending on the cham, you need to find out if he height is good. If the height is too small, maybe some cool pygmies.
You will need to implement a drainage system as well, there's lots of different methods on this site.
The glass might need to be replaced with aluminum screen unless you want to add a fan for airflow.
Also, you will need to waterproof the inside.
If this seems to mutch right now, you can buy a cool little cage for it through DIYCages.com or a local store and work on this little by little until your cham gets big enough.
