"As for DUB-EMA... It's not going to be part of my award ticket at all, so I'm not worried."
OK; just make sure that, if you're not going to stop over in DUB on your return, you leave plenty of extra time to make the connection in DUB. Because you will be traveling on separate tickets, you will not be protected if you should miss your DUB-BOS flight due to delay or cancellation of your EMA-DUB flight.
