my dream scenario would be a guy and a girl (actors) volunteering to do Padme
I'd volunteer to do Padme any day of the week (sorry couldn't resist)
If you have a good mike and a dead room then acting out the scene really helps, just don't stray too far from the mike, I've had people get carried away and ended up having to draw a chalk ring on the floor around the mike - None Shall Pass. If you move to far away the sound doesn't feel right even if the character has gone for a walk on screen.
To get an idea, take a look at any 'making of' for an animated film and you will see the actors standing at the mic stand, and they are usually acting their arses off while delivering the dialogue, but they don't stray too far.
