Looking at the Guru, Granzon seems like the only one that has probably more than a -enter arbitrary percentage amount here- chance at a perfect. He still needs Red/Blue to defeat Mario/Bowser though.
Some Guru's have what looks like to be the final four, but have Frog/Magus going to the final eight. Others have Cloud winning. I'd say someone out there might have the perfect bracket, mine probably would have been perfect had I not made some last minute changes I deeply regret. So, I don't think it's too farfetched that someone had the same thought process as me, but didn't make the last minute changes.
