Norway, Finland, and Iceland were not independent during the mod's time period, belonging to (I think) Sweden, Russia, and Denmark (?) respectively. Meanwhile those Central Asian states you mentioned are all most likely going to be covered in the amalgamous Uzbek civilization.
All the civilizations you suggested weren't very militarily significant during the 19th century anyway—though that hasn't stopped other people from submitting designs for similar civilizations in the Fountain, so if your design is interesting enough (they rarely are) you could try I guess.
In the Fountain, you are expected to post civilization designs rather than mere suggestions, if you want there to be any chance whatsoever of your suggestions being considered. Look through some other posts there to see the difference.
