That's a great idea, I'd buy some of that. No doubt many others would as well.
I'm sure this has come up in other threads, and I'm thinking VR has said they like the idea too, but it will take until SOME point after release before they have the resources to focus on doing this stuff. So we have to hang on till then for some Terminus art in our homes.
I still can't find any archives but "back in the day" there was one particular artist who made character portraits that were AMAZING.
There was another person who took your character and 3D printed them, then painted them so you had an exact stautette of your character.
Something like this could be interesting swag
