Dear Awful One,
"Yanno, that's exactly what someone asked Stephen King three days before he received the National Book Award for outstanding contribution to American letters."
This makes me wonder, if Stephen King contacted you and said he needed a new agent, would you be his agent?
No. Not cause I don't like him or his work but because I am not competent to handle the complexity of his agenting needs. However, the NEXT Stephen King who comes over the transom, you bet. It's an entirely different matter to grow with a client, than take on one who already has a complex body of contracts and overlapping deals.
