I need help from Fluther bakers modifiying a recipe!

I need to make some items for a bake sale, and I thought I’d try to cheat a little.

I bought some Krusteaz (what an awful brand name!) Pumpkin Spice quick bread mix, which calls for ½ c water, ⅓ cup vegetable oil, and 2 eggs. I’m wondering if I can substitute some canned pumpkin to make it a bit richer, maybe in place of the water?

I originally planned to make mini-loaves, but I can’t find the right sized pans, so I’ve bought some fall-themed pans and turbinado sugar for decor.

Any baking geniuses have a suggestion for me? Will the canned pumpkin work?
