My concept for a "new age" armored cruiser for 1905

I have had this idea that it would be amusing to have an armored cruiser with specs similar to the Minotaur, except a flush deck, tower mast, and a single funnel. The guns 9.2in and 7.5in guns would be in twin turrets. The 9.2in turrets would be at the ends, and one 7.5in turret would be superfiring, forward. The other four turrets would be on the sides. I wanted a 12-4in gun tertiary armament for torpedo defense. The armor basis would be 6in with a modest 23 knot speed. The technology would be oil-fired boilers with direct drive turbines. Of course, I used the "all-or-nothing" armoring philosophy. I entered the data and it "worked" in Springsharp. I don't know if Ian Ross-Gowan would think of this, but it seems reasonable, in a strange sort of way:
