No, because most maps do not have busy enough walls for someone to blend into the backround. Those that do have busy walls have different colors schemes in different parts of the map.
If there was a monochrome map with no lighting, then yes, one could make a camo design for that map.
The closest you could come would be ATCS with the colors averaged according to height, or a industrial-urban camo for Nexus6.
Also, camo is usually spelt with one 'm' as in camouflage, the non-abbreviated form. (Sorry, I only get on people for spelling if its the topic name or particularly horrendous)
