A very fair point. And I should have been clearer: it's not that there needs to be 12k people in one room all at once for an entire week. But I do think that there needs to be 12k people in the same room for one hour. Renting a stadium for an afternoon is very easily done these days.

This just can't be an email saying "Hey everyone, here's our culture rules now! Now get back to work!". Those get ignored. It has to be something that can't be skipped, can't be ignore, can't be forgotten.

I would point you to Netflix, a large company with a decent culture. They didn't ask every employee for input (AFAIK). They hired one person and gave her the time and resources and access to upper management and tasked her with coming up with the culture document. 12K people in a stadium for an hour or even 4 hours won't be productive like you want it to be. In the end only a few people will speak up because not everyone speaks up in a stadium full of people.
