Alright, it's really common even in the real world for more than one nation to have the word "Commonwealth" proudly displayed in its name. I personally don't see any problems with a nation sharing an element of a name with someone else. Just use the name your people are normally called every now and then to differentiate between the two. Also, I personally can also tell what Commonwealth is being talked about when its owner posts about them. It's not too confusing from my own perspective, really...
