Is it possible to combine all these stuff together and make a playable unity project ?

I use AssetRipper to extract whole game folder and open it with unity editor. It's exciting that I can spy all the level assets and design in editor. But there is no script data in inspector, I mean , wouldn't it be more exciting to see their parameter and another thing.
