In England though, those 6 teams will be getting an extra £350 million a year, compared to the other teams in England. They can afford to spend more, pay more, and I know that is already the case, but this makes the difference a lot bigger. With 6 teams already in the ESS, do you honestly think they are going to let other English teams join in?
The champions league historically has always required a team to qualify for it, and the new rules do give another way for the top European teams who have a bad season to qualify if there previous seasons performance has been good enough. No one was guaranteed a spot in the competition.
Maybe I am more of a casual football fan, but I don't go out of my way to watch football when its not Crystal Palace playing. I hardly ever watch the European Competitions, even though I have BT Sport. If I am at home, and not doing anything I will put the football on and watch it, but it could be a league 1 game, or a premier league game. I would not go out of my way to watch ESS or purchase an extra subscription to watch it.
I would have no problem with those 6 clubs not taking part in the Premier League anymore, it might mean the league loses some value, and the revenue from the broadcast rights drop, but again, I don't really see that as a bad thing.
If the ESS does go ahead, and the clubs get kicked out of their leagues, it would not surprise me if before long, it turned in to something similar to F1, where the ESS will sell that weeks fixtures to the highest bidder, and then from Friday to Monday, that city/stadium would host that round of games. I suspect there is some cities out there that would pay a significant amount to host a weekend of this competition.
As for the players, I suspect they are the ones who can stop this from happening. If there is a ban on them playing in international competitions and that ban survives all the legal challenges, are they going to be willing to leave those clubs, in which case the ESS falls apart if it does not have the best players, or will the 20, 30, 40% pay rises that come tempt them to stick it out?
