Like carve out a place between Russia, Belarus and Ukraine in the former Pale of Settlement. Establish a bunch of Yiddish language schools there. Have it become a center of Jewish culture. Sure, there are already Ukrainians, Russians and Belorussians there but there were already people in the far east too.
There was a movement for just that and a lot of Jews at the time thought the eastern oblast was a stupid ploy to just populate a region that had just OK farming land. Most stayed in Ukraine, which, in hindsight...
In fact didn't most of the Jews who went to the Oblast come from Canada?
