Ok will they eat all of it? Just the isopods?
Both of them should, yes.

It should be more than possible. After posting my ideas i did a google search to see what i could find. This thread (linked below) has a really well implemented version of your idea which he (the creator) says is pretty much self sustaining. He keeps birds in a cage above the tank but i'm sure you could alter the design to fit your frogif you got mesh the frog couldn't squeeze through. Well worth a look as it may just be what you need for inspiration. The bird droppings were apparently snapped up as food by the fish with njo harm to the fish.
A planted tank thats possibly an industry first.
He doesn't go into detail about how he made his upper portion but it could give you some ideas.
