Very interesting. So, the idea is to put Darth Maul inside one of the windows in Kamino?
That would be a great idea, but wouldn't Obi-Wan do a double take after seeing that?
Might it be possible for Obi-Wan and Lama-Su to walk across the camera, and then slowly pan down to Maul on a table. Hold it for a second, and then cut away to Obi-Wan and Lama-Su again, Obi-Wan oblivious to Maul's presence?
By the way, the Maul/Grevious concept reminds me of an original series Star Trek episode, "What are Little Girls Made Of," in which Dr. Corby, injured beyond repair, tries to put his soul into a robot and something is lost...
