Alright, I've managed to get the Champion's Body Armor piece by using the "runscript zz_dae_debug" command to teleport myself directly to the
Spoiler:high dragon encounter in the "Mine Massacre" quest
where you get it. So I used the "runscript killallhostiles" command at that point to kill the aforementioned High Dragon, and get the armor. I then managed to successfully teleport myself back to the prologue with that armor, so I can play through the game looking bad ass... sorta.
Which leads to my question:
Has anyone found out how to get the Boots/Gloves of the Champion via the console yet? If so, please let me know!
