I don't think so. At least not yet. It'd be an incredible way to combat the massive influx of migrants and refugees as it would fill jobs, provide revenue for those refugees, etc who are reasonably in Ireland, as well as bring in an invigorated group of citizens who have been seeing the entire situation outside of Ireland's viewpoint. Additionally, it would bring Irish people home as well.
Of course, I refer to the migrants and refugees in a ... polite... sense because we all pretty much know that this is a mix of both a Golden Horde as well as "not all really migrant refugees" so there's no reason to repeat it all over the place. We all know.
Half of my family comes from Sicily. No way I'd consider living there until they get the migrant issue back under control. I understand completely.
Dual, for a while at least. If I move over there and love it more, I'd give up the US citizenship because you have to pay double taxes.
