Can I make the game create more townies?

I don't like manually populating the entire town, I create a few families that I think would be an interesting addition and then I want my sims to meet and discover random new townies.

But I've been playing in Moonlight Falls for five generations now and my Sims know everybody/have hooked up everybody lol plus a lot of their extended family is around now, so it's kinda boring. I don't want to move them out to another town, I love it here and have a great legacy house.

I use all the essential NRAAS mods. Can I do something to have more random townies spawn?
