I think you will be better off getting it into the ground. I once added about 4 inches of leaves straight onto the garden. These compacted down over winter and the ground took a long time to warm up in the spring due to the density of the leaves, resulting in a soggy mess.
Now I shred everything and till the whole garden in the fall after adding the leaves.
