I did a Netherlands run when 1.9 dropped, trying to get high SOL. You have your own little India to invest at the start so plenty of stuff to build, while keeping all buildings in your own market. I spammed trade centers in Holland (it has 95% MAPI in 1836) that are insanely profitable, basically acting as middlemen for the entire dutch market.
It's not extremely low GDP, but I managed around 20-30 mil for some time time until I got swarmed by immigrants (despite being an Ethnostate). It would probably be best to close your borders if you want to keep your GDP low, but turning Holland into a 40 SOL utopia while immigrants toiled in frisian ports was pretty funny.
