GG would have still lost. As the novelization explains, the only time Kenobi was ever really in trouble is when he attempted to counter GG's '20 strikes/second striking-speed' solely with defense/Soresu--he was about to get overwhelmed. When Kenobi switched tactics and went a bit more on the offensive, however, he disarmed(hyuck hyuck) the good General with a fair amount of ease.
