Well, I don't know that Jedi would allow themselves to be distracted by some energy releasing. I don't think it has to be a huge effect. It could look pretty cool though.
AND I could get rid of the cheesy CGI Maul splitting in half. He could start to fall down the pit, then an energy blast could engulf him. Obi-Wan watches, the blast stops, he switches off the lightsaber and runs to Qui-Gon. Badass.
