This is taken from another website after I asked about modding with dragonborn items in the save
I'm not sure how the request thread is but if the person filling the request has the Dragonborn.esm from the Xbox DLC they can do all the normal commands with all Dragonborn items. The only restriction is Skyrim will crash if it tries to render new model, FX, etc.
If the user who is fulfilling the request doesn't have Dragonborn.esm, everything new from Dragonborn will be lost. The Dragonborn all items chests, the Dragonborn spells, everything.
I will ask him directly how to do it but it will be tonight before I get a response. Try searching around and maybe between the two of us we can come up with something.

I wouldn't recommend messing with Marketplace files. That is just asking for trouble.
As far as people not using batch files, there may be some out there who would rather put the commands in on their own, to verify that they work, or simply to improve their own skills. The same way that a person will use a manual hammer and not just spam a nail gun all the time.
I hope this thread takes off a bit once DB drops on the PC, but i don't think it will until something drastic happens. For whatever reason, folks seem paralyzed by fear of getting modded for simply asking about save game files, on a site that has save game files available for download. Seems a little silly to me.
