As you say the Greeks and Ottomans are close to a choice - do they continue to take part in the dreadnought race or not.Nice ship !
As expected the French and Italian are responding to each other programs (even if it's not necessarily the main reason). And since the weight constraints are heavy, both nation are loosing the torpedoes launchers !! I think the French design is slightly better and more balanced than the Italian's
I note that, if both country have the cash, they can spam one such ship (or their respective improvements) every 14 month while staying inside the treaty limits.
Even with the number of ships ordered (5, 3 French and 2 Italians), it will change the balance of power in the Mediterranean. They give a renewed advantage on Greece and the Ottoman ships. And it might force the RN to respond with fast ship in the theater.
On a side note, OTL the French used the left over machinery from the Normandy class ships to re-motorized the surviving Courbet class ships during the 20's, specially the Courbet which had 2 engine fires, and the Béarn Aircraft carrier. It wasn't a resounding success as the refitted battleships were limited to 19kt, but ITTL, they have more engine sets (without the Béarn), so they might be tempted to go full oil firing (against the mixed machinery of OTL). A more comprehensive refit is probably necessary to make the Courbet class anything more than overpriced training ships.
Arguably, the Greeks would be better off swapping their pre-dreadnoughts for a pair of decent cruisers and leaving it there. The Ottomans can be masters of the Black Sea without too much effort. Preferably some destroyers for both.
Tricky one the Coubets. With France and the Dantons gone, they can build 126,000tons (9 'light battleships'), before they have to think about scrapping them to stay within Treaty limits - i.e. not before the current Treaty expires. They might therefore want them to see another 10 years' service.
On the other hand, they're probably the worst dreadnoughts in service with any of the major powers, so why waste the money when they can build new ones.
The somewhat better Bretagnes could benefit from modernisation, and in a Treaty world they're going to be around until the mid-late 30s.
