Personally, 3 noble is the maximum I can play well. I currently have 4 and I find myself having at least 2 being pure sheeple. I would not create a new character even if I could.
That being said, if someone has the creative input and the time necessary to do it, why not? It doesn't remove anything for me.
The point is that it won't fix a problem. Rather give those who want it an extra char.
