Evidence of this is that no one has yet uttered one negative comment about the Lama Su voice, and most people I've discussed it with think it's really great (based on the snippet we've seen from the trailer).
To be perfectly truthful, there is a quality to Anakin's new SOTDS voice which is extremely reminiscent of a martial arts movie which has been dubbed into English. Don't know what causes it, but it's definitely something related to the voice itself and not the technical details of the sound mix.
The other thing you have working against you, and this may be hard for you to believe, but there are alot of people who actually like Hayden's performance. And then there are those who may dislike Hayden's performance but have had five years to get used to it, and no other voice juxtaposed with his image will ever sound quite right to them.
Now, you know that I've been following this thread practically since the genesis. I've contributed music and helped in whatever way I could, and I have nothing but respect and admiration for the work you've put into this and for what you're trying to accomplish. I consider you a friend, and I passionately believe that the other aspects of this project are 100% pure gold. I continue to be pleasantly surprised by the things you're still coming up with. You've succeeded beyond expectations in every single area except for the voice. And unfortunately, I know it's what you've worked on the hardest.
The thing is... it is the one aspect which will make or break this project.
At this point, my friend, as controversial as all of this is, I think it's clear you've got to devote some serious thought to doing a version which retains Hayden's original voice in addition to the one you've already dubbed. As repugnant as it is to you, it may satisfy those less bothered by Hayden's performance. That way, people will have a choice.
You know that if you don't, then as soon as you release this thing someone else will immediately pull it apart and do a version that may not be up to the same level of quality that you'd like, and by that time it'd be out of your hands. I'd say it would be better for you the editor to do it before anyone else.
Sincerely,
