Can I put a uromastyx with a pair of bearded dragons?

I have a male giant German beardie and a female sandfire beardie and wanted to know if there was anyway I could let a Uromastyx join them? Someone is offering me one for my alligator snapping turtle and I want to trade but I won't if I can't have those 3 together. My beardies are 2 years old and the Uro is a year and a half I guess.
