I don't think Claude should do it at all. He's good once a year at the interviews, and we all look forward to that; if he was an advisor each week, he'd either have to tone down his tough approach (taking out the thing that we all love about him) or keep doing it every week, which would mean the novelty would soon wear off.
I agree with the person who suggested Ricky. I also think the first winner, Tim Campbell, would do a good job.
