I just realized Strawhats and Revolutionaries do basically the same job,subverting countries governments. So it would be cool,if there will be an arc devoted to the RA,to show the SHs going to an island where Luffy meets the classic princess of the arc and the story leads us to believe he is going to do the usual thing,freeing the country etc. maybe he also gives an epic speech,then suddendly turns out the Revs were planning something since months and the Coup D'Etat happens quickly,with the RA not needing Luffy's help at all! It would be a little subversive and self-aware humor,but i guess it wouldnt be Oda's style,so it probably wont happen. Maybe we will just get the SHs and Revs working together to save some country,if the two entities have to form a bond.
