As suggested by julianus heraclius, in this thread I want to discuss in which way the transformations in the administrative structure of the Empire before and after the Tetrarchic Reform, can be implemented in Restitutor Orbis, that is, how to depict in the Map of RO the passage from the Old Provinciae to the New Diocesis.
Here the Map of the Provinciae of the Empire in 117 AD from Wiki:
The Provinciae at the time of Severus (From Barnes: ‘The New Empire of Diocletian and Constantine’):
Creta et Cyrene – Aegyptus – Arabia – Phoenicia – Cyprus – Syria Coele – Mesopotamia – Palestina – Cilicia – Cappadocia – Galatia – Bitinia et Pontus –Asia –Lycia et Panphilia – Thracia – Poesia Superior – Poesia Inferior – Dacia – dalmatia – Macedonia – Achaia – Epyrus – Pannonia Superior – Pannonia Inferior – Noricus – Raetia – Agri Decumates – Germania Superior – Germania Inferior – Alpes Maritimae – Alpes Cotiae – Alpes Garaiae et Poenninae – Bellica – Gallai Lugdunenis – Gallia Narbonensis – Aquitania – Britannia Superior – Britannia Inferior – Baetica – Hispania – Lusitania – Mauretania Tingitana – Mauretania Caesariensis – Africa – Sardinia – Corsica – Sicilia – Numidia.

My Proposal about the new DIOCESES in RESTITUTOR ORBIS:
My proposal comes from an old Italian Mod Of RTW 1.2, called Mare Nostrum: The idea is this: When the player reaches the Age of the Reform, he saves and he exits from the Game and then he goes in the folder of the Maps, here he finds a New Reformed Map, he charges the new Map on the current Map of the Game, he deletes the Map RWM file, and then he restarts the game, he charges the saved game and voilā! He is in the Reformed Empire of Diocletianus!!! 
Pro:
- Not many scripts, easy for the player.
- Quick and elegant solution for the Administrative Aspects of the Reform.
- It can be possible because the new map doesn’t change the towns, the rivers or the roads and so on, so IMO it is an easy way to bypass the issue.
In the Italian Mod they used this system to prevent the destruction of the Dacians by the AI: The spirit was if we cannot change the AI we must force the AI to do what we want, so until the year 100 AD, the terrain to reach Dacia was impassable.
Cons: I do not know if the idea is practicable 
(IMO it is, anyway I’m not a modder so…)

(*) Laterculus Veronensis or Verona List is a list of Roman Provinces from the times of the Roman emperors Diocletian and Constantine The list is transmitted only in a 7th-century manuscript, which is preserved in the Chapter House Library (Biblioteca Capitolare) in Verona. The most recent critical edition is that of Timothy Barnes (1982)
