It just wouldn't be the sport you're trying to "improve." It would be some new sport.
I don't know if you've noticed - come to think of it, you haven't, obviously - but outdoor club soccer in this country has increased in popularity as it has moved CLOSER to - not farther away from - the generally-accepted "world standard."
"Americanizing" the game, as if this is 1994 and you think you have to appeal to people who don't like soccer because you don't think there are enough people who are, is ridiculous.
Every single thought you have in your mind is wrong.
