When Cable decided to make his own floating island nation out of the debris of his own orbital space station - just roll with it - the nations of the world did not respond with great admiration or respect. That's right, the world that hates and fears mutants did not take too kindly to a mutant having his own powerful space-age country. If Fox wanted to take the interesting geopolitical slants to that story and input them in a Deadpoolsequel, that's up to them, but there's a lot of material ripe for Deadpool's particular brand of brutal quips designed to tear down the self-imposed serious facade of comic book storylines. When Cable first started up Providence, Deadpool somehow got himself caught up in Cable's 'bodyslide' (see also: teleportation) rig meaning that anytime one of them teleported, the other was dragged along with them. Deadpool ended up being a sometimes ally/sometimes d*ck to Cable, and a film where Deadpool basically ruins Cable's utopian dream sounds like an entertaining one to me.
