I don't agree with you, I think you fail to grasp the social aspect and tradition of European football. This Americanisation of the game won't easily fly here.
There are rivalries, banter, fan interactions which were cultivated throughout the decades, you can't just pluck teams out of their natural leagues and expect things to stay the same. Betis and Seville is arguably the biggest game in Spain, yeah the legions of Barca and Real fans across the globe don't give a crap about this game but still it's part of the culture, it's part of what made LaLiga attract global attention.
Yeah, end of the day money speaks louder than anything but expect a lot of resistance from traditional fan bases. If something like this is to emerge, I reckon new teams, akin to North American franchises will have to be established.
