It's more likely then you think.
It's gained in popularity among the latinx population due to teams in Miami, Phoenix and Dallas which all have large latinx populations. Not to mention the influx of Latino NHLers. Austin Matthews has actually shown interest in playing an exhibition game as his mother is Mexican.
The entire country is in agreeable centralized timezones and travel isn't too bad so it's not entirely untenable. Obviously the easy pick is Mexico City as its the highest population center, largest metro and not to mention a capital city. However, it is quite far south into Mexico, I think actually the more ideal locale would be Tijuana.
Tijuana is on the border with California, which makes it easier to travel too, it's a beautiful coastal city, meaning the players would like to live there and it's the second biggest city in the country, dwarfed by Mexico City sure but it's still millions of people.
The sport of Hockey itself is growing in popularity in Mexico as well as a result of NHL run initiatives to teach the sport to kids in the country and their own International Hockey Teams have been making wonderful strides.
Obviously there are a lot of issues and it means ANOTHER border and countries COVID laws to manage so it's not going to happen soon but maybe in ten years, I wouldn't be surprised.
