Most of the stories you mention in relation to the Iliad don't actually appear in the Iliad, you know. Also, if anything can be described as "a collection of stories", it strikes me that Books 9-12 of the Odyssey (Odysseus' stories about the Cyclops, the Laestrygonians, the Lotus-Eaters, Scylla and Charybdis, the Cattle of the Sun, etc.) fit the bill much better than anything in the Iliad.
