Yeah, the first word that comes to mind with the idea of a 'team crossword' is more along the lines of 'chaotic'.
My attempts at crossword creation usually result in either a terrifying hodgepodge or a meticulous, laborious symmetry. I can't imagine what more than one person, without constant communication and obvious synergy, would create.
Not to say it wouldn't be possible to make a good one.
At the same time, I don't think that the crossword template is as readily-convertible as a quiz template. There would probably have to be a fair bit of coding done to make something like that begin to work, and the crossword side of things is far from perfect as-is.
It's an interesting idea, no doubt.
