I'd be tempted to think of it in terms of Palpy as the corupt mayor and the Jedi as Coruscant/galaxy police force. some of them are crooked and some aren't. It'd also be interesting to see anakin actually slide a little rather than simply decide to be the bad guy at the drop of the hat. It'll be interesting to see things from his POV especially during moments where he seems to do morally wrong things without even a thought. Although i guess that even in ROTS rather than justify his actions he changes the subject so things like that could carry over.
What time period would be present day? I would think it'd be more interesting being close to the actual events and have him reflecting a lot on what had happened. You could even have him thinking back from some point in rots, say just before he leaves for mustafar. The narration post this could be picked up by someoune else, say maybe Palpy?
I'll read it all over more in depth later on but it sounds good so far...
