That would actually be quite fun, and would be quite creative too, as there would be a huge amount of possibilities with the amount of items on each page. Screen grab of the page you were allocated as your first post would be a good rule, nobody would be able to claim their page looked different because of monitor size etc that way.i still think a lighting challenge would be the funnest.
Each person gets a random page number and has to compile a scene using any or all of the models on the page. shading and lighting.
