Sure it would. Back when the originals came out light-sabres were supposed to heavy, a lot like Excalibur, very heavy weapons. That approach could've easily worked today instead of the stupid prancing, spinning and jumping about. Of course the fights would be a little faster.

Take the fight scene in the Bond film 'Die another Day', sure the movie's crap but this scene is pretty good. And the characters get tired and out of breath, which we didn't see at all in the fights in the prequels. Whereas in the light-sabre fight in Empire strikes back, we see luke and vader get tired and stressed out. And the characters in that scene actually look like they are trying to hit each other, instead of their swords.

But then the main thing would be to have something going on between the characters, but that's the job of the screenwriter.
