Natalie, Skye *is* the project leader for Galicia, which includes some portions of what is now Ukraine but was then simply part of the Russian Empire. I don't know whether or not we already have (or need to have) a Russian Empire project, but such a thing would cover a vast region, an order of magnitude more than present day Ukraine, which, alone, is significantly more than the portions of it that were included in Galicia.
The amount of effort Skye has been expending to bring order to the chaos of Galicia is monumental and I could not imagine putting an imposition on her to tackle the even more massive task of categorizing the entire Russian Empire. I do agree, however, that the best way to do this would be for someone (better, a group of "someone's") to step up and volunteer to take on this major task. Perhaps a proposal to create a Russian Empire project might be an appropriate prerequisite to proposing specific categorization of it.
