It's the only mod that I know of that deals with Cyrod, and here is how:
As for making modern Cyrodiil more empire-like, there are plenty of mods that do that. For starters, I'd use:
Open Cities Reborn (OCR) - revamps cities to open format in Tamriel worldspace: http://oblivion.nexusmods.com/mods/33003/
Better Cities for OCR - adds more building to OCR and revamps Imperial City: http://oblivion.nexusmods.com/mods/16513/
Arthmoor's villages (creator of OCR) - villages are downloaded separately, but here's a list of all of his mods: http://oblivion.nexusmods.com/users/684492/?tb=mods&pUp=1
Roads of Cyrodiil - adds new roads and bridges: http://oblivion.nexusmods.com/mods/20218//?
ImperREAL Empire Forts - Adds working forts for legionnaires: http://oblivion.nexusmods.com/mods/22965/
Note: I haven't used the forts yet, but I plan to on my next install.
Hope that helps
