Question Is it possible to link game object to prefab counterpart?

Let's say I have exactly the same objects hierarchy structure duplicated in several scenes. Something like the following

Code (csharp):

1. └── Canvas
2.     └── Panel
3.         ├── Image
4.         ├── Text
5.         └── Button

Then I realized that I want to slightly change the structure and I want the change to propagate to all scenes. For example add another button

Code (csharp):

1. └── Canvas
2.     └── Panel
3.         ├── Image
4.         ├── Text
5.         ├── Button
6.         └── Button 2

Is it possible to make a prefab from the first scene, link all other objects on other scenes to the prefab and then modify the prefab?
I want to avoid deleting the game objects hierarchy from the scenes and replacing it with prefab, because it has fields exposed and dependencies are injected through Inspector. I would want to link existing game object to the prefab counterpart with the exactly same structure and then modify the prefab. Is it achievable?

 

Same!
