Somebody did this a long time ago just around the time the PS3 was first hacked open. It would be interesting to be playing some of the source ports for doom. Zandronum, Zdoom, GZdoom, Eternity, many to list. You can do a mountain of editing with the decorate lump files for those first 3, I loved messing with that stuff years ago, and they've probably gone miles since.
