Based on your "no more than 4 per country" idea I notice that your plan leaves out Atletico Madrid (I assume it's them, it could be Real) and one of the Milan clubs. Both those clubs would be happy for it to proceed without them whilst Minsk, Dublin, Helsinki and others have a club in the top two divisions? In what aspect is this idea built on sporting competition? And in what aspect is this is a goer when you tell people that they won't be playing Real or Atletico, or one of the Milan clubs but will be playing Bohemians and HJK instead? You also have a dot on Cardiff, who play in the English league and therefore wouldn't have been invited, unless the powers that be have decided that the side 21st in the Engish second tier is a viable and necessary option and have asked them to leave.
And, what actually happens to the domestic leagues under this idea? Do they just exist without important clubs involved, or do they just disband? Either way, complete destruction of a century's worth of tradition and culture so that we can have a bizarre league that isn't based on sporting competition but on a desire to stick dots on as many parts of a map as you can.
This why I said "roughly". If you check my original post, I have not excluded Atletico Madrid and neither of Milan clubs:
As long as the state owned clubs are left out, I am 100% in favor of the European Super League. I would love to see it with 3 tiers and 72 clubs (maybe even 4 tiers and 96 clubs), promotion/relegation of 4 clubs between the tiers every season, no more than 4 clubs from one country and no more than 2 clubs from one city (so most of the European countries are involved), a professional refereeing organization with the best referees in the World, and of course, a fair distribution of the ESL revenues to all the involved clubs ...
With 3 or 4 tiers, it is very unlikely that the very top European clubs will play at first the likes of Bohemians and HJK, even though that wasn't such a bad experience in the European Cup, while it still existed. The first tier of the ESL at the beggining will most likely have clubs from England (if they join), Spain, Italy, Germany, France, Portugal and Holland, with clubs from other countries qualifying in time as they grow.
The fair distribution of the ESL revenues will allow for the clubs with century's worth of footballing tradition to become strong once again, so we won't have the ridiculous scenario of Bournemouth outbidding AC Milan in the transfer market ever again.
As for Glasgow, Dublin and Cardiff, they will be specifically targeted by the ESL, if the English clubs don't join it. Maybe Belfast too, and certainly both clubs from Glasgow.
Domestic leagues will continue to exist, of course. They will have do decide if they still want to be owned by Abu Dhabi, Qatar, Saudi Arabia and the likes, or they want to return to their century's worth of tradition and culture that no longer exists ...
