If you just twiddled his voice setting he would still be the same droid with the same memories.
If you keep the voice but remove the memories he becomes a blank slate with the same voice.
Like I said, this depends on the idea that droids' personalities are tied to their memories.
If Leia had all her memories removed you'd care right?
So why not Threepio?
See above.
Heck, there are people who lose their memories without personality change!
That being said, we're both beating this to death. I'm in favor of bluescreening a person in an OT Threepio costume into the PT as a member of Amidala's staff, something like that.
