And Bombadil has been referenced as "older" than the the rings, which puts him as outside of the effects of the Ring's powers and the world around him.
I'm not sure what you mean by this. There are many characters older than the One Ring: Gandalf, Elrond, Galadriel, Treebeard... age is certainly no protection. Bombadil's mastery over the Ring (or more accurately, its lack of power over him) is because he has no interest in any power beyond what he already possesses.
Bombadil wouldn't fit in the movie for the same reason that he's a bit out-of-place in the books. He has virtually no connection to the larger story, and is out of the story (for good) as quickly as he appeared. The character is really an inside-joke for Tolkien's children: the character was based on one of their toys.
