Someone should take it upon themselves to track and monitor every xwing player in the world and where they reside on the globe. Denser populations of players would receive weighted bonuses to moving the tournament needle closer to their location. Once all of this information is collected, and posted for peer review, for player approval, the tournament location should be held at this composite spot (Note: should this location fall over a body of water, you will need to procure some sort or portable floating island stable enough to host games. Power will also be needed to charge laptops and tablets for the app, cellular and wifi data will be the responsibility of participants). If on land, simply rent and possibly build a suitable venue for the tournament. This is the preferable way vs the island.
Now that the perfect neutral location has been decided, you will next need to focus on advertising, as well as prizes for the winners. You'll need to set up rounds and brackets as well as procure volunteers or paid employees to manage the games. You'll reserve the right to sell video rights and replays to whatever organization you do choose so that those who do no attend cannot complain they have no way to view this most perfect event (why the **** aren't they here anyhow, amirite?).
Any permits required by local governments (county, state, country, etc) will need to be handled as well.
This will ensure that you really stick to FFG and in no uncertain terms, show them how to do a real tournament. Honestly I'm surprised this hasn't been done already, it seems like less effort that what some do on these forums
