Chameleon Enclosure/what bug can i keep in it

Hi, I basically just inherited a second hand chameleon enclosure, and I was wanting to know if it would be good for either an arboreal tarantula or a tailless whip scorpion. Even if I had to make modifications on it to keep the humidity in more. It's one of those average mesh chameleon enclosures, mesh all around with a removable black bottom.
