Yep. They've got a lot of Garlean characters to bring to the table and get involved in the recovery efforts. They can also showcase the might of magitek next time there's a big threat to be dealt with. FFVII had Scarlet indirectly involved in saving the planet, after all, due to designing the cannon that penetrated Sephiroth's barrier and allowed Cloud and his companions to reach him.
Garlemald could also become quite the trade powerhouse through creating and selling civilian focused magitek devices to slowly increase the quality of life across the board. If they play their cards right it could take the form of something similar to IX's steampunk style rather than futuristic/militaristic to better fit the aesthetics of the other nations.
