I ran into something interesting that has, I think, some good material for some alternate history, though I am not able to do anything with it currently, since I'm bust with "Tomorrow's Mountian."
In the pre Great War years, Brazil and Argentina were interested in selling their dreadnoughts, and several nations were interested in buying them, including Greece and the Ottoman Empire. Since these ships were built already, unlike the soon to be stolen Sultan Osman I and Reşadiye, they could have reached their buyers prior to the war breaking out--or even been sold while the war was ongoing, if the Ottomans and/or Greece were neutrals.
If anyone thinks this is a fun possiblity, please--run with it.
Certainly a pair of dreadnoughts would serve Greece better than the two undersized predreadnoughts they bought from the USA, and the Ottoman Empire already having two (or more) dreadnoughts might make Britain consider handling the theft of the dreadnoughts in a different manner.
