Anachronistic ship designs

I found that when I was teenager, it was rather fun to take real ship specifications from the 19th Century and early 20th Century, and give them more modern characteristics. Instead of muzzle loading guns, say, give them more modern breechloaders (perhaps 45 or 50 calibers long). Instead of masts and sails, give them WWI-looking masts and bridge. Maybe give them a flush deck and raked bow. Don't have iron armour, but give them Krupp Cemented armour. Keep about the same dimensions, as that is part of the deal. You can substitute smaller breechloaders for the larger muzzle loaders. Make drawings or wargame pieces. I have also tried creating photos of them with a certain amount of success. This is my photo of the Nelson and Northampton armoured cruisers:
