I don't think the audience is Jar Jar -- he' s not really the main character and he's even less available for that role in the MagFan edits.
I like your suggestions, but I also like the MagFan solutions. I vote for alien voices and for a total overhaul of the final battle where only the scary and cool shots are kept and the goofy/funny ones are dropped. With the Amidala plan being overhauled, there's less reason to allow any of it to succeed. I think the Jar Jar beats on Naboo are there to cover the lack of anything strong happening between Anakin/Qui Gonn.
Qui Gonn is the Main Character and it's his p.o.v. that we take as an audience -- feeling his interest in Anakin, feeling his frustration with Jar Jar, etc. It's his story and that's something Lucas didn't bother to follow through on.
This edit will be the first, as far as I know, to try to take advantage of this problem and turn it into an opportunity.
Episode I is the story of Qui Gonn.
