NCU (no crystarium challenge) has been completed in Japan, and it was recently completed with the english version as well.
Here's a link to the gameFAQ's thread and page at the point where the game was actually beaten without using the crystarium:

And here's the youtube vid of him beating the final phase of the final boss:

I think it's initial equipment part. I've never seen that be possible. But with that criteria absent I've seen damned near everything else mentioned and this looks a bit elaborate for a hoax! It basically relies on ridiculous item spamming.
You did make it pretty darn far though - beyond a part that was thought to be impossible. Almost to the very end of the game.
I have yet to even play FFXIII myself, but the Doom-thing (which, from what I've understood, results in a Game Over when the time runs out) sounds like biggest issue.
I suppose a FFXIII challenge would have to require a handicap that doesn't make your offensive capabilities suffer too much, in order to get past some of the Doom-bosses in time.
Edit:
Good news. (Though I won't watch the videos myself yet, as I haven't even played FFXIII normally). >_>
