What you could do is cut off the outlands, and have the slums be the "new sewers" with loot spawns and reb closets and the sewers could be the "new outlands" with the public storage chests, and relative safety from CP searches.
Give CPs the ability to do random searches, and block sweeps, and not only would the tighter map have the small playerbase bump into eachother more, but the looser rules would give CPs more ways to bully suspicious civilians, and potentially have them be less bored, and therefore be less likely to leave.
