Medieval 2 Total War Assassin

Assassin's Creed Total War
I am a little shocked that no one has made a mod for this already. The assassin’s creed, the first game, takes place during the third crusade. The second Game takes place during the renaissance and this allows players to choose between an early and late period campaign.
The campaign maps could be large. Like the medieval total war 2 map and maybe some more land added like in SS6.3. The maps could also be centered on the areas. For the early areas it would be like the crusade map and the later would be focused around Italy.
For the early campaign some suggestions are:
The Assassin Order http://assassinscreed.wikia.com/wiki/Assassins
The Templar Knights http://assassinscreed.wikia.com/wiki/Templar
The Teutonic Knights http://assassinscreed.wikia.com/wiki/Knights_Teutonic
The Knights Hospitalier http://assassinscreed.wikia.com/wiki...ts_Hospitalier
The English http://assassinscreed.wikia.com/wiki..._The_Lionheart
The Turks
The Mongols
The rest of European kingdoms
For the later campaign some suggestions are:
The Serine republic of Venice
The kingdom of Florence (The Medici family)
The Assassin Order in Monteriggioni
The Papal States (Rome)
The Templar Knights
If anyone knows of an assassin’s creed mod already can some 1 please post the link because I have searched google many times trying to find one.
