No, I like the idea of keeping this project limited to Ukraine (similar to the other regional Jewish projects listed at the Jewish Portal project site).
I also think "cities" is misleading. I see under Belarus at the Jewish Portal, that they use the word "communities": "Jewish Communities in Ukraine"?
Oscar and I have renamed the project more or less along your suggestions.
We should really have an umbrella project for Ukraine and also have reference to the administrative districts during the Russian Empire since that is what determined where they could travel and who they could marry at the time when the majority of Jews lived in Ukraine prior to the diaspora of 1880 - 1920. Meaning Volhynia, Kherson, etc.
Private User - My Jewish ancestors lived in Poland (formerly Lithuania), Lithuania, and the Ukraine. In Lithuania in the towns they lived in, the population was 40 - 75% Jewish. That includes Vilnius that at one point was 40% Jewish population. 3 millions Jews emigrated from the Russian Empire between 1880 - 1920. There are more Litvak Jews overseas than Lithuanians in Lithuania. Lithuania has already recognized that the Jewish people were a significant part of Lithuanian history. I don't know as much about Ukraine yet.
In terms of an umbrella project for (Jewish) Ukraine, I think this could be it.
I really like the idea of having individual sites for the various administrative districts. Partially because I just started one for Volhynia:
Jewish Families of Volhynia (Wolin) Gubernia
Taking Randy's suggestion to beef up the Jewish Genealogy Portal, I've been collecting the Jewish Ukraine projects that I've found and putting the links on the Portal. We could also put these links on this project's main page.
Please start the projects for the other administrative districts (like you, I'm not an expert on Ukraine--yet :).
I've added the link to Ukrainian
