Hey! I would love to do it like that but the problem is the scenes are images of renders. There's no real-time cause-effect possible in this game because of how Ren'py engine operates. It
can be possible but it would be too taxing on resource and time. I would want these changes to affect/block/influence other scenes and dialogue too, but that is something I am planning to do after the game has massive amount of content, so that I can start polishing the game and don't feel the need to prioritise content.
So the answer is simply, it would take too much time to make it so that each modification affects pre-existing scenes.
