Perhaps we are getting close to groupbuy. A lot more people have expressed interest in Russian or some other Cyrillic based layouts recently.
Thing is, to make it best for prices, would need to do a flat profile. That way it is easy to use the same set for Russian, Moldovan, Serbian, Bulgarian, etc since they all have many of the same characters but in different places. Maybe include Greek as well, since has many of the same characters too.
