Greetings!

I know that this topic isn't connected to this map or the whole Iron Gauntlet update, but I have to discuss it with a mapmaker, who is interested in MvM. I didn't want to add you unnecessarily, so I'm making this discussion here for my goal.
Long time ago, I was interested in TF2 content making. I'm bad at doing anything in 3D world, so working in Blender (I've never learned it) or Hammer (I tried my best) failed. The only thing left was making concepts, including weapon and map concepts. The weapon concepts aren't interesting, because Valve makes the stats. But the maps... I have a totally-made and a halfly-made map concepts.
I would like to talk about the first one. I like gangsters/mobsters - I have a Heavy,a Scout and a Spy loadouts based on this. This thing inspired me to make an idea about a hideout map. Here's everything I noted in a text file:

I'm not a talented image editor, but I tried to make posters and word jokes about popular mobsters. Here are the results:

I don't know, if you will like this idea, and it isn't needed to be made. The only thing I would have liked to do is sharing this with someone in the Workshop.

Cheers!
