I don't think fans want anyone portraying Castiel who isn't Misha. That idea doesn't sound like it would work. I also don't think the quality of writing has been maintained, a lot of people say it has gone down.

But yeah, a young Bobby and Rufus might be okay for a spin off. Maybe even a young Crowley would do. I don't know.
