Well, I am doing something similar by changing Dex voice and dialog, but I would like to redubb Obi-Wan asking Madame Jocasta, saying I’m looking for a planet system called Geonosis (instead of Kamino). The plot should work without Obi-Wan ever referring to Geonosis by name, but in my opinion it would be a bit jarring, if they were always talking about “a planet” or “a system” instead of simply calling it Geonosis.

Thanks to your replies, I’ll keep an open eye on McGregor-interviews and maybe watch the Geonosis arc from TCW again. Splicing together single syllables on the other hand is something way beyond my editing-“skills”, putting together sentences from different scenes is already difficult enough.
