Killing nationalism is a process that will take a long time and is only really being done because of Ireland being a direct territory. I don't really think it would be applied to other areas.I expect Bertie will marry Marie- if only because it’s the road not taken in OTL and so potentially more interesting.
Beyond this, the narrative so far seems to be one of more focused and successful reform efforts. We seem to be ending up with greater military efficiency. And if “killing nationalism with kindness” is seen to be successful in Ireland, could it be rolled out in other territories?
Beyond that, it’s early days!
