Replacing blueprints on the server at runtime

Let’s say, I have launched my game as dedicated server and I want to adjust some bits of game logic in my blueprints. Is there any way to replace some actor blueprints on the server without restarting it and without losing current state of my game world? If I could modify a blueprint, save it as a file, replace it on the server and the server picked it up and restarted the state of related actors, this would be really great and effortless alternative to integrating some scripting solution.
