Why don't you make the whole section of the movie about Anakin turning into Darth Vader, Order 66, the fight between Obi-Wan and Anakin, etc. into a bad dream? Anakin could wake up at the end and there could be birds chirping in the background. And then end the movie with that. You could make the whole storyline of Episode III pointless just by doing that :)

You could include the birth scene and Padme dying as part of the dream. Then you could use the scene of Anakin waking up from his dream about Padme, therefore making it seem like he doesn't care about the part about him becoming Darth Vader and killing all the Jedi, just about Padme.
