Prince of Britannia Emperor of the Chinese Federation

What if Lelouch's audience with the Emperor after his mother's death went differently. Lelouch is sent to The Chinese Federation, where he is to marry Empress Tianzi (Who, for the sake of the story, is 7 years old, not 2 like she would have been in the series).
Lelouch X Harem later in the story, there will be no lemons nor limes in this story.
