The answer to your question is NO
I understand how it's hard to receive event Pokemon, but it is not because of where you live - it is the date and time. Events for a game WILL reach worldwide, but will be removed due to it only being available for a limited time.
For example, OR/AS's shiny beldum event when the game was released.
In America: November 21st 2014 - January 14th 2015
In Japan: November 21st 2014 - January 14th 2015
In Europe: November 28th 2014 -January 14th 2015
As you can see, the Event will reach around the world, but in different times. Since each event is available for a limited amount of time, you can not receive an event Pokemon when it is finished.
Hope I helped! :)
