Well let's have a try with this "Admiral's Galley"!
Then let us slide to full AU!
Here is the ship as it was commissioned in 1906.
I didn't retained the (supposed) real turkish 1904 project. Instead i maintained a 4X280mm main battery using the german Braunschweig class main turrets (big up to ReiAyanami) and increased the secondary 150mm battery only to 8 guns. This increase, as it was not compensed by a decrease of the main gun caliber, involved the suppression of the third 76mm battery and the reduction of the fourth 57mm battery. As the main turrets were wider the front and rear structures were closely spaced to the funnels. And the "Admiral's Galley" was removed.
Then here is the improved Adul Kadir class battleship Abdülmecid I as it was commissioned in 1908.
The Ship was laid down in 1904 at the Constantinople dockyard and intended to be a full sister ship of the Abdul Kadir. As work go on on his older brother his design was improved with a new 170mm secondary battery of 6 gun in turrets and 4 in casemates. To improve the fire arc of the main battery the structure were even more centered with the suppression of the rear mast and a new forecastle in a german style (big up to ReiAyanami once again) joined with the front funnel.
After commissioned in 1908 it proved much more efficient than the original design and plans were made to upgrade the Abdul Kadir to this standard. Nevertheless nothing was done until the first turkish build pre-dreadnaught was sunk by the British submarine HMS E11 on 8 August 1915 (instead of Barbaros Hayreddin).
