There is no entrance on the opposite side of the wall.
As you can see, the pod that Pein's second body came out of wasnt from the "Animal" pod, but from the "Human" pod...right beside Pein's "Heaven" body.
It was a awesome theory that you came up with man, but seeing that the "Animal" and "Human" are on different sides , your theory may be incorrect...unless you were tired and accidently labled "Animal" and "Human" on the wrong pods.
It could be that the Entrance just closed after Pain had laid down, and then opened back up when he got up. We all saw him open it with his bare hands somehow. Maybe he didn't want anyone to see him while he was trying to change or maybe he didn't want anybody to see his other forms.
As for the Theory. It is good. I like the fact that in his Heaven form, he was able to control the weather like a storm god or something. I also like the fact how the Fat body could be Hell. It seem true that your theory could be correct especially after seeing Pain use the possible animal body. That would also answer Jiraiya's question on why he is only useing summons.
