To split Sicily you'd need to use a magnified sub map, otherwise it'll get too tight and crowded. You need to be able to fit several army stacks, several agents, titles and the fortress into the available space. The Pocket Mod map has a problem with Tripoli being too small. To fix this I would probably have to either increase it's size or use a modified maptex.tga with a sub map - which I'd rather avoid.
