If you have to mix, I would suggest researching Polychrus sp. lizards. I have some housed in a 36" tall vivarium that are doing very well with mint terribilis. They are a very slow moving, deliberate genus that acts very similarly to old world chameleons. Here's a video:

I know many people overseas keep anoles in with dart frogs in larger vivariums, but I have no experience doing so.
Before you decide to mix, I would strongly suggest taking your time and doing proper research. it's not an easy task to meet the needs of multiple species with different husbandry requirements in one vivarium.
