The dumpy tree frog in the whites tree frog of the exact same frog. the dumpy tree frog would not do good in enclosure this small and it will need a lot more bushy plants because it lives in a more dense type of a forest than just the plain forest floor. If you buy a green or a gray tree frog they will be wild caught so no matter what you do the American tree frogs are wild-caught and the dumpy tree frog will get too big for this setup in about 2 to 3 years. I think your setup would be great possibly for a tomato frog or some type of Reed frog. You might be able to search for a smaller captive-bred tree frog species. Josh's Frogs and LLL Reptile are highly favored in regards of captive frogs. There is also a Mourning gecko that you could keep it stays small and you could potentially have a group inside the enclosure. You could also attempt fire belly toads.
