Nope, Sony and Microsoft are very, very reluctant to allow modding of games on consoles. They'll only do it under certain circumstances (Halo's Forge or Little Bigplanet were built in builders they had direct control over and UT3 which I think was a bit of an experiment that has since been dropped)
With a game like Skyrim where mods are intergrated into the game world and have a potential to mess up the game if you do something wrong. They won't allow it.
Not to mention a whole host of technical, legal and logistcal issues.
There's already on going thread that includes a direct confirmation from Bethesda that console mods won't happen.
I'll go find it. edit: Heres the thread ---> http://www.gamesas.com/index.php?/topic/1160482-console-mod-dlc-possibility/
And the quote from the Community Manager Gstaff.
We like seeing the mods that are made by the community, but we have no plans to make them available as official releases.
Similar to Morrowind, Oblivion, and Fallout 3, the tools for Skyrim are PC only. There's no plans to release a version of the Creation Kit on consoles. If you're into modding, we suggest you go for the PC version.
