This should work indeed. Anyway, you can always try, I believe when you can't add a node, Cassandra will throw an error.
You can then do some cleaning, remove the joining node from the ring if it is still there after the failure and clear data "rm -rf /path/to/cassandra/*" on the joining node that failed. Then try adding it again when it is the good time to do it. But basically, adding node to distinct DC are operations relatively independent and it should run smoothly.
