If there was enough content, you could have chapters. Such as architecture, portrait, landscape. . . Have it limited to one, two, or four pages per person.
The problem would be financing and coordination and even we had a set of books made, who would they me marketed to? If its just for each of us to have a copy, would the benefit of having a physical copy out weigh the cost of a low production run of books? Do the people in this thread really care about seeing and paying for someone else's photos when they could come on here and look for free?
I think its a cool idea and would love to do it but I am not personally in a place where I could help finance something like this unfortunately. If the wife's new company takes off, then it wouldn't be a problem but we are currently living on my pay alone which will be a problem shortly if something doesn't change.
Maybe a go fund me type campaign?
First we would have to see who in here would be willing to submit photos, then talk to a company about potential cost.
