First, welcome to HBT! This is a fantastic site with very helpful people.
My first thought is that a pumpkin ale doesn't need a lot of hop character. Plus, dry-hopping will give you aroma but will not add any bitterness (you mentioned the IBUs).
With that said, if you really want hop aroma I'd suggest something spicy and/or floral to complement the pie spices. I personally dislike Fuggles as too earthy, so maybe the Tett or Willamette or even Glacier if you have them.
