Absolutely! There are many species of iceplant which will grow in your climate --- they just need more supplemental water, but are still quite xeric, and rapid growers. There must be lots of nursery resources in Las Vegas, and loads of on-line ones as well. You probably want to avoid the more cold adapted ones from mountainous regions of South Africa, since they have less heat tolerance.

please dont plant iceplants,

they are sterile...
