Well damn. Maybe once you get enough posts, you can ask around and see if anyone else exported it because I'm pretty sure someone did at one point.
The only suggestion I can give at this point is to see if you can change the road layout to something more realistic. I dunno how much of the original you want to change, but I do know that if realism is your goal, it'd be better off to make the road layout look like this, where the roads highlighted in red are kept while the roads in the yellow circle are done away with. It always annoyed me how a lot of the San Andreas towns had that dumb layout where you drive in and it's just a spaghetti bowl of streets. At least this way, you've got a typical main street that's going through the town and connects to two other roads, which is pretty common in almost every small town. Just dot the buildings from inside the yellow circled area along the street going through the town and wham, you got good stuff with room to spare for more neighborhoods because how can a town that small house 6,412 people.
But again, that's ultimately up to you and how much of the original you want to change for the sake of realism. I'd totally be onboard for that.
