Alright so here is what I know and this is what I am thinking. First of all if you want to use console commands on xbox saves. Obtain A copy of Skyrim for the PC (Not suggesting anything). There is an easy way to do this. If you use an xbox drive file browser like say the one built into Horizon, 360Revolution, or Modio you can get to your save if placed on a thumb drive. Use Horizon to go to the content of the save and get the .dat out. now change the .dat to a .ess. this is the file extension for the pc saves. now place it in the save folder for the the PC version. load up the save on the pc version and go to town with the command console. when you are done save, change the file extension back to .dat, reinject it into the save on the thumb drive, save rehash resign, and load it up on the xbox. all the stuff you changed will stay including if you change the scale on an NPC or something
