I will create a mod whereas the player can start in 1933 and have the option to play with Italy and transform the country to S.P.Q.R through events just as Germany in 1933 (elections, flag prohibitions etc.) the S.P.Q.R will have claims on different regions that previously belonged to the empire.
Basically, if you choose in 1933 you have the option of building up your own version of S.P.Q.R, there will be events and decisions that will let you take different roads, place claims and establish relations!
It won't be an advanced mod, and if anyone wants to help I'd be glad..
((I will keep expanding this post.))
