Architectural Minimap

Would it be possible to create a minimap on my level through blueprint that looks like an architectural floorplan? I haven’t had any luck trying to use 2d capture cams with post processing, as they don’t get a nice clean, orthographic view of the level that I’d like. Any help would be appreciated!

I’m not experienced enough to suggest anything, but maybe there is a way to use custom depth to achieve something similar to this?
