Cutting out the Gungans completely is actually quite easy. Just remove every scene they are in. They are only mentioned in one other scene that they don't appear in - when Jar Jar and Padme talk. That scene can also be cut as it is no longer necessary. Jar Jar is simply left on Coruscant before the climax :D

Not actually because when the Jedi meet Jar Jar for the first time he tells them that he would take them to Gungan City and then it becomes inevitable to meet the Gungans. The only way to make it possible is by redubing Jar Jar to say Naboo City instead if Gungan City and that is the difficult thing.
