Hi Haden,
They would probably be just fine with lots of cover, lots of greenery overlaying forked branches. (of course, lots of greenery is lots of fake leaves to scrub too). Have you thought about using plastic hides? There are some nice rock ones that you could possibly mount up or put in a little shelf area? Super easy to clean. I also use cocunut halves for hides, they clean fairly well. Just some ideas!
My amazons that do have a hide, I keep it on the floor of the enclosure, they usually sleep there and then spend the afternoon/night up in the branches under the fake leaves.
