Co-op mapmaking has been suggested over and over again before. I think it's a really good idea and would be innovative in the mapmaking community. It could also change how maps are made and how it will look like.
However, there are certain complications when it comes to PB2's publishing system. It would be hard to know on how the map id would look like and how the rates would affect mapmakers that helped in creating the map.

Who needs that sh*t? Just make a button that will grant full map access for certain friend of yours. ID will be the same and there aren't any rewards for participating. It would be up to map owner to credit the co-creator or not.
