I'm not sure why they haven't talked about plans like this. Sure PGI would need to approve maps, but the dedicated /talented community that is BT/MW would be able to produce enough maps with every climate / environment imaginable at an alarming rate. Hell, if the community got their hands on a decent map maker, their map making team would be working 24/7 on just making sure the maps are bug free and up to par.
Any map that isn't up to par, PGI could just send back an email to the creators saying why it got rejected and the list of grievances. No doubt the creators would then go back and improve the map, fix the bugs, etc.
Players feel the need for larger maps? They'd create them. More brawler orientated maps? Larger, urban maps? Space maps? (like Lunar from MW4 or the water asteroid mission on MW2 Mercs) You bet your *** the community would make them.
