even housing different sub-species together can bring about disaster. territorial disputes in the rainforest are not handled as "well" as humans. normally a fight to the death ensues. ok, so they are just like us...lol but look, i'm going to be realistic here, you are going to do with your frogs what you want to, so i can help you with the build itself.
more details are needs such as what material you are planning to build it from? if you plan on running an ultrasonic fogger, you are going to need a water reserve, so a false bottom would be better than a hygroton base. how are you planning on sealing it to keep humidity levels stable? heating options? you also have to decide on a pump for your water feature, and how you plan to filter the water.
i'm going to suggest to you to browse through the different build logs on here and on the net and you can get a better idea of the challenge you are up against. any questions, feel free to ask.
