Winnable by the OL? What set up would you use?

I chose Crow Hags on Main Road and Giants on Crossroads. Heroes decided to go to the east to avoid obstacles and scorched fields. I used Giants to block the path and sweep-stun. Crow Hags to harass from behind and prevent a lot of healing. Elite Crow Hag's Death Omen was great to further slow down the heroes with immobilize, stun and poison conditions as at that point heroes had no means to remove conditions. I moved Valyndra's Shadow directly to the villagers. Won this easily.
