It's not a good idea to let people customize flags because inevitably there will be people creating obscene images and ruining it for everyone else. It happened on system games like Call of Duty to the extreme. I'm sure you're intentions are pure and it seems like a good idea to make a neat flag; but for every cool design you come up with, some moron is going to make a ♥♥♥♥♥ or naked lady and start ruining the game.
