Terrain Time or How to make something into what it is not

I am looking to attempt to create the train station in Kharkov in 1941. I am going to base the building off of the really nice GameCraft miniatures model of their large government building. The thing is big in 15mm. I can't even imagine what it is like in 28mm.

I just finished the assembly of the building. It is really nice.

These are the back and front of the building. I plan on using this as a multi purpose "government" building. The intent is to have items that I can add or take away from it to use it for different things. I have been trying to find good pictures of the building from 1941. Those are hard to come by. Here is an aerial photograph that dates to August 1941, several months before German troops arrived.

The building I am looking at is closest to the tracks. There is a large courtyard in front of it. The basic layout has not changed much. Modern views are similar but the main train station has been upgraded. The only period photo that I found of the station is this one. I think it is a shot of the building from the rear and not from the courtyard.

The modern station is quite different.

What I have does not duplicate either building. But what I was thinking of extending one of the towers on the model to be a clock tower. In the period photo, you can see the columned tower on the right side of the building. The thought was to make a block of balsa and decorate it up to look like this tower. Then get a clock face from some doll house kit and make a clock face that would face the courtyard area. Put magnets into the roof of the existing tower and the bottom of the clock tower to hold it in place. But still be able to remove it for other things.

Once thing that I cannot see from the period picture is if the building has a name on the front. The modern one does and I was thinking of copying that and making a wire frame to hold the letters on that could be set on the facing above the stairs on my kit. The modern building also has a pair of statues there on either side of the train station sign. I was thinking about getting 2 10 or 6mm miniatures and painting them white and sticking them up there as decoration. Just trying to find the right figure first. Something heroic looking holding a teardrop shield seems about right from the pictures that I have seen.

I will never have the time or money to get it to match, but I think this is a useful middle ground. Any ideas or helpful suggestions?
