The only issue I have with the blue on blue is that supposedly, by the time of the duel, Anakin has given himself to the dark side. If he has joined the Sith, why would he still have his blue sabre? I hope against hope that Lukas does something else and either has Anakin leave it in the temple after the raid as a way to denounce his aliance to the Jedi or have the duel start out blue on blue but end up blue on red.
