I don't think so. Or if the title is used it would always be preceded by "former."
On closer inspection Obama's potential pool of running mates is rather shallow if he is to:
a) stay on message as the insurgent anti-establishment "change" and/or "post-partisan" candidate
b) regain any electoral advantage with groups he has not done particularly well with (white women, hispanics) and/or be a strong campaigner
c) gain policy credentials in areas where he is perceived as weak (national security, foreign policy) and/or add governance experience
d) maintain his advantage on issues he can use to attack McCain
e) work well together, or at least be perceived to
f) a combination of two or more of the above
g) and of course be potentially a good President
While she's good for B; A, D and E would effectively eliminate Clinton.
A and E may or may not also rule out Clinton endorsers like Ed Rendell, Wesley Clark and Ted Strickland.
To fulfill A and D effectively eliminates some of the proposed Senators due to their Iraq votes. Biden, Bayh. It would remove an area of attack for Obama in November.
I don't really get what, if any, Edwards would bring.
I think Bill Richardson probably fulfills the most positives without racking up too many of the negatives. He has foreign policy experience, he may appeal to Hispanics, he may help to deliver a leaning Blue swing state, he doesn't have a vote on record for the Iraq War, he has executive experience as a Governor and backed Obama early on despite incurring flak.
Who he picks will probably be indicative of which of these he values more/most.
