desert iguana with collared lizard?

I currently have a male blazing blue collared lizard in a 4ft enclosure. I know they have been successfully kept with chuckwalla before. And desert iguanas have also successfully been kept with chuckwalla. But has anyone kept collared lizards and desert iguanas together successfully?

If it won't work out, then I won't do it. I'm not usually into mixing species but I was wondering if anyone else had experimented with this mix?

Would a 4ft enclosure be enough room for this?

Thanks in advance for any advice!

I was at the living desert in palm desert California and they had all three species together but they were in a huge cage like a 4x6x4. I'd just make sure there all healthy and watch for aggressive behavior if any aggression occurs I'd separate them
