...Who would it be and what title would you have them write. This would be a ongoing monthly title (past or present) with a promise of at least 24 issues. The writer can not be one who is currently deceased.
I would have to go with: Chris Claremont writing The Uncanny X-Men.
This would get me back to reading the X-Men books again. It has been several years since I picked one up and from what I read here I am not missing much.
I miss the days when the X-Men were in Australia, on the run and "hidden" from the world.
