There is a mod on pcgamemods.com that enables you to make items off of the workbench. One of the items you can create is the cut-scene Revan Robe (w/hood, mask, cape, etc.)
One think that I tried to do was to extract a hooded revan robe from a game save and incorporate it to an itemcreate.2da file so you can use the kolto tank or the workbench to extract it. No such luck yet though. If I get it working, i'll send you guys the file.
For now, just go to pcgamemods and download the Revan Cutscene Robe mod and this should work fine.
