No, not really.
An interview doesn't give anyone the opportunity to really address your actual skills and promise as a researcher. It could serve as an "additional" data point (the same way that alumni interviews at private US schools offer additional information), but I don't think someone who interviewed you, famous as they may be, would provide helpful feedback that couldn't be provided by someone else who knows you firsthand. (One of the things that a reference letter asks is "how long and in what capacity have you known the applicant. "I met her for an hour once" is not an answer that inspires a lot of confidence.)
(Then, there's the additional issue of arranging the interview—I doubt a "famous name" would agree to such an interview in the first place!)
