I think it would be best to finish the tournament online with the full bracket. So that there are at least 6-7 players with 4 rounds and a decent Buchholz score.
Because the final is still far away, and it is unknown how many players will be from each city. There may be rejections, replacements, cancellations of qualifying rounds, etc.
Let's say, if Aldegira's wife doesn't let him go, and Forrest goes on a bender, who will go from Ukraine?
+1, I don't see anything wrong with finishing the tournament online. And Forrest won't go on a bender, he doesn't drink :).
