Hey! This is a lot like my favorite Headcanon! Except it happens to every country and its actually Multiple Personality Disorder (MPD). This type of MPD is different, as the affected are countries, not human. When the other player takes over, the body changes with the mind. The most popular second players (such as America or Italy) are actually the result of constant (and often uncontrollable) cycling between first and second player. Cool right? X3
