I don't think its impossible. All it takes is a good writer to write good stories, and the comic is good again.
That's all comics ever need.
Plus, I hope future writers working on BP don't have an axe to grind against Hudlin, or at the very least, keep it to themselves. Anyone who takes it upon themselves to "salvage" the damage is only going to complicate the character and his story by undoing some continuity they didn't like, rather than just ignoring it and moving on.
