Thalassar likely won't ever get added since it requires waay too many NPCs, but I like the idea of a "Thalassar Border" Region on the east side of the map with a few new mechanics, like some hostile anthro NPCS (Bandits/Highwaymen). Isolde could roam around this area and visit Silverpine on a Weekly/Bi-Weekly basis. There could also be two Border Guard NPCs that switch out every week that can take certain goods for market trades (They take different items than the crate, to keep the crate relevant.)
