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

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.

Do not ever rename cities. Lots of them appear in the script quite apart from in the reform section. If you really want to you will need to search the EBBS for the city name you want to change (external) name, if it doesn't appear in the file then it may be safe.

so hopeless; what about changing the name pahlava to parthia?
is it hopeless either?

You could do that, but I don't know why you would want to do that? That's like changing "Romani" into "Romans"...

just an example ...
as you know the dual cty of babylonia quite similiar to seleukeia ctecifon
like buda and pest(e)
