Changing city names by playing other than Romani? advisable or CTD inevitable?

[Atraphoenix]

Hey dudes; I just wondering to change Seluekeia to Ctesifon and Baylonia to Seleukeia as historically Ctecisifon was on the other bank of seleukeia after I captured them while playin with pahlava.
as most know we can enable change_city _name in I think descr.strat whereever it is..
As I do not play with romani I will not have any reforms like romani as as far as ı know automatically eb script cahnges for exampla taras to Tarantum etc.

do you advise to do it by playing other than romani (I mostly play with pahlava)

and I would be happy is there anyone after I captured historical homeland of parthians any chance to rename pahlava as parthia or have to script work again?

all comments will be welcomed.
