EDIT: another possibility is to split the map in two:

1) Norther Tunisia plus Pantelleria and Sicily;
2) Souther Tunisia with Kasserine pass and Mareth line;

opinions?

Another method would be to do as was done in "Kurland", "Bessarabia" and "Slovakia" : use always the same map but make variants where only a part of the map is populated.
For instance, using the same "base map", three variants : completely populated, populated only in Northern Tunisia + Sicily and Pantalleria, populated only in southern Tunisia.
