I agree that this may not be a simple feat for some.
That's why I wrote that the spokesperson should be somebody with experience and the support of a club.
We will need twice as many tables as teams. Once the first storm has quieted, I expect a maximum of 6 teams, that will be a maximum of 12 tables.
Usual Epic tournaments seem to max about 8 tables. If you get the support of someone organizing Warhammer tournaments - which are usually much larger - you will have the venue and the tables covered. This leaves the terrain, which would have to be built or borrowed, but nobody said it would be easy

And did I mention the spokesperson should be somebody willing to commit himself to this and preferably with the support of a club and experience in organizing tournaments ?

The setting of players will not be possible as I wrote in the text that the numbers of the nations and the players will be determined randomly. So you might know before hand that your player number 1 will be playing number 1 of nation 2 and number 3 of nation 4 and number 1 of nation 5, but you do not know before the tournament who those players are, not even who your number 1 player will be.
A Swiss system is not well suited, as it will break the equal number of games against all other nations, as well for the team as for each single player.
Also if you incorporate the nation thingy info the restriction for pairing the Swiss system will quickly not longer apply, because the restrictions will prevent the strict following of best playing best.
If we would opt for a European Single Champion I agree, we should use the Swiss system, but without restrictions, i.e. players of the same nation may kick each other out. But this should be fore mostly a team event, seeing players of different nations playing each other.
If you go with 4 games, you can do 3 on Saturday and 1 on Sunday. This will allow you to end the tournament before 15:00. Starting at 10:00 (it's Sunday after all), 3 or 4 hour game, will be 14:00. That leaves an hour for price giving and saying good bye. So people staying will have an afternoon for sight seeing and the others will have a very good chance to get home and still call it Sunday.
You can even get two games of 3k in on Sunday and finish before 17:00 - games from 9:00 to 12:00, 13:00 - 16:00.
Finishing at 17:00 let's you still get the late flight (not all destinations might have a late flight). People traveling by car can switch drivers, if they have to get back the same day or next morning.
Basically it will be possible, if people want to do it. If just the thought of going abroad exhausts you, this might not be for you.
And suddenly it was not so easy any longer to get a 4 player team for a nation with a population of 80 million
