wow, im not really sure what to tell you. there are not many handable lizards that could live out there life in a tank that small. aside from leopard geckos which you know about its going to be hard to find something. most desert dwellers need ALOT of space. they need large enclosures to help them thermoregulate properly. you might be able to house a collared lizard(Crotaphytus collaris)but i am not sure, and i am also not sure if you can handle them or not. i just did a quick search on some of the desert lizards i could think of and thats the only i could find that could live in a smaller enclosure. good luck though
