Another point about the UVB lights, UVB rays cannot pass through glass or plastic. So, if you do make a sunroof or skylight, that will not supply UVB rays. (I'm a reptile person, can ya tell?) There are many ways to protect critters from the burning hot basking bulbs and fixtures, though it will be more difficult with birds in the picture. In my own habitats where the bulb is inside the cage, I have it out of reach. That, of course won't work with birds. Another option is something like this. Also, in a setup like this, it might be tempting to use something like a heat rock for a source of heat. I avoid these like the plague. Reptiles have been burned on these many, many times.
I think this project would be much, much easier without birds. I also really like the ides of butterflies rather than birds, though some of your reptiles may attempt to eat them.
I'm sure you will do this anyway, but make sure you research every species you plan to add, and make sure they are okay being with other species. (Most people in the reptile world, especially those in North America), will tell you to never mix species. Though it is difficult, it is possible if you have the right knowledge and experience, and if you have enough cages if everything go awry.) For instance, avoid adding chameleons. While they are absolutely gorgeous and very interesting creatures (I happen to have one for those reasons), they are very easily stressed out, not only by the presence of another of their kind, but also the presence of non-Chameleon species. There are many reptiles that are solitary by nature, and it would probably be a good idea to not try to put these in an enclosure such as this. However, I think turtles would be an awesome addition, either water turtles (though they may try to eat your fish) or box or wood turtles (but they are more expensive).
One thing I just thought of is I wonder how the humidity would affect the birds. I know there are tropical birds, but I think most of them wouldn't be suited for this kind of enclosure. This is may be another reason you might want to consider butterflies.
