QUESTION : Mr. Lee dubbing for AOTC

[saruman12]

We all know that Mr. Lee is fluent in italian, spanish and french
and still pretty good in german. Why doesn`t he dub himself in his "big" movies ? I know New Line made the mistake of not
asking him to do it which he would have done, i am sure.
I hope Lucas lets Mr. Lee dub himself in Episode II , because his role is even more important in AOTC than in The Fellowship of the Ring. His usual foreign voices sound rather "dull"compared to Mr. Lees great, original deep voice.
Juan or anbody that knows something about it :
Was Mr. Lee approached to do such a thing or did he suggest anything ?
