Behavior switch command

So I'm playing Minecraft bedrock and I think it would be interesting to have a command that would allow you to change the behavior of a mob for instance the creaking would act like the warden. I think this could be beneficial to the game because it would allow for some more creativity for instance you can have a friendly Warden who acts like a dog. And it could help allow for some more world building if you're making your own lore in Minecraft. Which is what the game strives to do is allow you to make your own story.
