Expand the map to India, make the extra unwanted terroritory unpassable and make the region part of the Sahara region. Now you've taken care of areas that we don't really care about. As far as re-allocating provinces, make cuts in several regions. From the Isles, take;Erain, Corieltauvae, Cambriae, Cornovae and from NW Africa take Phasania and Gaetulia. Mod the Africa part of the map to put a sahara province border between a fully expanded Carthage and Alexander/Ptolemy. I have personally never seen the AI take Auwjogotanoz, the small island off the coast of of the Scandanavian peninsula, so for all intents and purposes I'd say scrap it. You now have 7 provinces for india, and if it's argued more is needed, the only overallocation of provinces I feel is in Gaul/Germany, so you might want to take one or two from there.
A few more proposals. This should definitely be based on BI, and incorporate the loyalty ratings. Give Rome a counter faction, and make the late game interesting. The emerging factions will allow Baktria to form properly, as well as Pahlava, and any other appropriately emerging faction. It would also allow hording, which would be applied not only to those typical factions you expect, but even to give some depth to perhaps a political party that was driven from it's home. Perhaps use religion as a crude form of culture, with Greek, Roman and Other since these two particular cultures were the ones who dominated regions and slowly converted other cultures to their own ideals. Obviously a persian won't be happy about a barbarian, but neither culture tried to really change the other. Do cities have loyalty in BI? If not, I'd suggest client rulers, with some decent rates of movement for players and keep the current client ruler set up for AI. With client rulers for all, with family members representing generals only, you could give more depth to ruling a city compared to being a battle commander. If when Alexander dies, if his empire is formed, it will collapse into the appropriate factions. If he dies before his time, then depending on how much if anything was conquered, have the 3 generals emerge as contenders in Greece itself. I'd suggest play time be from the death of Alexanders father to either the current end game date, or, slightly before the historical time for the Imperial reforms, and cut them out in favor of giving more units to these new factions if the unit limit from the removed factions doensn't supply enough units to the new factions.
[edit - wrong button] Reasons for not including the KH, it was a alliance of city states, better represented by rebels I think. Other italian factions, nobody else on the peninsula from what I know had a taste for conquest quite like Rome. I noticed Illyria suggested, they only came together for a short while, and were interested in piracy not conquest so much, and thus perhaps give a large naval port to the rebels there with the ability to produce some strong ships. Or a lot of them, whatever. Casse are gone, what role did they really play? Did they ever invade the mainland? Did they even dominate the region? Not really. Arvernii: I believe the Aedui at this time were a stronger faction no? Either way, while it's regrettable to cut them, I again feel their better represented by rebels who oppose a individual tribe. Perhaps if we want a change of tribe there remove the Aedui for another Gaulic tribe that may seem more appropriate. Saka was my last faction that I feel ultimately should be sacrificed, in order to give romans late gameplay value, a counter faction and representing the civil wars. If the Saka were truly a hard competer, they would have been in the core collection of factions EB has had since .7x I feel.
