I see this as a chance to expand the Wizarding World, to explore an discover new Ideas

Try this on for size
In the South the Duello is a popular gambling sport which might be viewed as sort of Wizard Boxing. It would have famous arenas and Super Star Wizards on par with the athletes of the muggle world

In America could even be a replacement to Quiditch, likely it'd be rough an almost brutal

And what if the broom had been replaced by the skyboard 50 to 60 years ago?
Well I shouldn't say replaced, perhaps augmented
It would be surfboard like and young magical borns could be seen sky thrashing like skae boarders
New York would have a hidden place like Diagon Alley that was huge when compared to it.
Central Park now there's an odd feature in such a crowded city, "What if there was a Magical reason?"
