Hello Maximus of Phoenicia, welcome to the .Org!

I am not entirely sure what you are asking. Do you simply want to have R:TW cities instead of M2:TW ones, or are you asking for accurate historical city maps? I know that in R:TW it is possible to create customized battle maps for individual cities, so that for example the battle map of Rome actually imitates that of historical Rome. Peninsula Italia implemented this, IIRC. Problem is that these maps are fixed, i.e. they do not change to represent upgrades or city growth over the duration of the campaign. And obviously Rome and several other major cities changed a great deal during EB's time-frame. Furthermore, it is a great deal of work to create such maps (never mind researching them), so the EB team did not bother with this.
