I have also been looking at this kit, I just brewed the Orange Creamcicle Ale from them. I am looking to add something to make it something other than just a cranberry wheat.
I was looking at food pairings and white chocolate has jumped out at me but not sure how the flavor would do in a beer without lactose such as a milk stout.
I have had Harpoon's Grateful Harvest and it was a solid beer you knew you were drinking a Cranberry beer. Also had the Sam Adams Cranberry Lambic , that's when I discovered that I do not like Lambics.
If I get this I will be getting it soon, I will update when/if I brew it.
