No city map = the 20 tiles a player can put workers or not.

This may be possible. On the other side you can choose the manage all
your cities with the CMA ;)

I know that the CMA will only manage one city and that the behavior in
such cases as mentioned above is undefined. The settler management
agent does do a global allocation of tasks. The question is (if a tile
has become "free" and two CMA-cities want to use it) which city should
get the tile? And another questions is: should it be possible that a
CMA-city gives a tile away if another CMA-city needs it more? The
natural way would be to measure the change of the fitness
method. However there is a problem: the re-calculation of a set of
overlapping cities can be without limit. Another solution which has
nicer properties is:
 - each city has a level
 - in a given set of overlapping cities there no two cities which have
 the same level
 - the allocation of tiles is based on the level
