It would require a different pronunciation for sure, and you’re probably right that it simply isn’t worth the effort. Thanks for trying, though!
As for 3PO, Poe, and Rey, I’m not sure what the problem is in generating them. If Eleven labs truly hasn’t changed anything, then 3PO and Rey might be hopeless. This is because they admit that the generator has an issue with accents, in addition to the fact that Anthony Daniels paces his words in a very unique way with 3PO. For Poe, we’d just need to locate audio samples of Oscar Isaac speaking in a slower, less yelling-ish way. So basically an inside voice.
