I wouldn't know so much about conversion but Ireland is one of the most modern countries within the EU in terms of culture, law, ethics etc.
Obviously the country is on it's knees at the moment in terms of the financial structure; however, if you're a half decent pilot and get a job in the industry over here - you'll be rewarded a hell of a lot more as a pilot than in the US (unless you're a well established US pilot) and will therefore be higher up the food chain than many in the country.
Just my 2 cents but you've probably chosen one of the best EU countries as a future base.
