I would hope so. I don't think Racontours or the Dead Weather could headline, and the Whitestrips porbably just because they haven't been around in ages. If it is just him and a backup band then it doesnt really seem like the biggest act on the list.
Jack White is pretty well connected in the industry though, so I would expect him to have some friends.
People keep asking "will he be playing White Stripes songs, or songs from his other projects?" Well, what is he going to do? Play his solo album in it's entirety. Will that even fill a headlining set? I think to fill a headlining set he is pretty much going to have to play other music other than that from his new album.
Really, how hard would it be to get Meg White on stage? Sure her schedule is probably open. If not, it wouldn't take much for any drummer to poumd out a few basic beats.
