Can I make a huge sand thingy for my hamster to burrow in? HELPPPPP? - hamster sand pit

I just got a cage for him and want him as comfortable as possible and as close to their natural habitat as possible for them ...
I've heard live in the desert .. So I thought of digging a deep pit of sand kind of thing for them .. What other good things I have in her cage for their fun? I have a point and saw a swing and a wheel there's more ... I also have a huge maze for them and some ramps ... What can I do? Please answer! Help!
