Well you could always port it to the ps3 yourself. I did see a mod like that maybe a year ago. Just google it or just download the mod from nexus, put the esp/esm into the Dragonborn or Dawnguard folder with the .bsa too (dev_hdd0/game/BLUS30778/USDIR/NPDRM/Dawnguard/DATA). If your mod have any loose files (textures folder, script, etc) you need to backup your game first and then put the loose folders in dev_hdd0/GAMES/SKYRIM/PS3_GAME/USDIR/DATA folder. Now have fun with your mod
