I think it would be cool to see somebody with a saber versus someone without one.... my suggestion is:
Darth Maul vs. Jango Fett (with all weaponry/full working jetpack) and the environment would be the rooftops of Coruscant. If that one doesn't strike your fancy, then howzabout: Durge vs. Jango Fett (location will be, hmmmm, Streets of Theed)
Seriously its easy to see..
You see, GL once said Anakin is the chosen one, so he's like all powerful and stuff, you know like all powerful can't be beaten, you know like stuff..
So Anakin had like children you know, and those children like helped kill the Emperor, but Anakin did it all because he is the chosen one and stuff... But one of his children was Leia, you know the girl in the cute slave girl outfit you know, so she like sleeps with Han and stuff, so Han is like dating the daughter of the Chosen one.
The emperor doesn't stand a chance
Somehow that makes sense
Darth Plagueis returns to claim his throne from Sideous.....After all would be easy to write in since Plagueis could create life through midichlorians....ya know if he was that powerful in life Im sure he was able to retain his conciousness in death and become a ghost....to still influence over the living as Yoda kinda put it....and if he has influence over the living that means he could still "influence" a womans midichlorians to recreate him.....! Tis a thought
