A few people have done some stuff in the vein of what you're doing with the meditation scene. I hope that it's okay that I reposted Marvolo's and GoodMusician's clips here. Marvolo's clip incorporates some lines of Liam Neeson's from Batman Begins originally done by ADigitalMan.

GoodMusician's clip uses an Episode 3-style Force Vision showing that Yoda knows what happened with Anakin and Obi-Wan's duel and that Padme's life is in danger.

Maybe these ideas could help you if you can't find someone to do a voice-over for you.

Did you change the audio for the saber clashes, or did you change them visually?

..the big work was to give sens to the cuts for enhansing "the story telling", trimming some "lines" etc..

Tell me about it. There's so much bad dialogue.
