I am kinda away and will check your mod in a few days. But if I like it, why not incorporate it, if you are fine with it? It does not impact the gameplay, it's not controversial in any way, so why not just make it official?
Stay tuned 
Well, I'm worried about the timing between updates. I do this as a personal hobby, I like the feeling of doing something right. When I look at a random name that I KNOW it's some random gibberish I lost the immersion and it starts looking like a placeholder rather than an identity (which it technically is) I may see some article about grammar or cultural details and the first thing I think of is if it's implemented in the mod.
That is my own level of detail. I change it constantly, sometimes overruling previous changes. I do not want anything from my work feeling out of place, especially if it involves the work of other people (like yours, one I admire and enjoy.)
We could talk this, that is for sure. But right now, some nations are kinda on the "wip" stage. For now, I'm 100% sure that working as a submod is the best outcome. At least, for now.
You can use my namelist as you like! But like I said, Lithuanian (the example I put on the other post) is far from finished. I'm busy too right now, but I work on it from time to time.
Let's keep in touch!
