Do I have to start a new campaign to play Ice and Fire?

I hope we do have to restart with a new hero. I also hope that we can play just the DLC and that essentially the DLC is a stand alone scenario.
My hero that I completed WotN with has far too much money and items to make an interesting and challenging game. And I have no interesting in replaying any part of the existing WotN campaign, which bored me to tears.
