i wasn't aware of that experimental scene, ill have to check that out.
the edit was just a quick file bash really, but i have always felt that the duel would be great if it could be closer to the one in ESB, with obi wan being overpowered like luke was, and his defeat of anakin could be anecdotal of his defeat at the hands of dooku or possibly grevious. ambitious, radical, and miles away from anything i could achieve.
some music would help, especially if lead from some tense dialogue, then the music could be composed of the wind and fire like in the ESB gantry.
i also would love to see the whole mustafar affair devoid of padme. bonkers plotwise (the twins and her retirement from the story would be set before) but then obi wan would run to his former apprentice, seeking to redeem him (like luke does) but fails.
the movie would end as SSWR roughly laid out with him appearing to steal baby luke from a coma induced padme and flying off into space.
