You can request a name addition by using forums or mail to support.
The problem is that those names will be only available to be used for the "Youth Name Change" feature. That means you will have to change your player names manually and only for 3 of your players.
The system will continue to select from the default database when creating new players for Kuwait (using the unrealistic names for your people) and it will not use any of the new names that you will propose.
In order for this to happen, there has to be a database update, and as far as I know this is not a priority for the Crew at the moment...!
