If you want to try, call Kevin Swords at the IAA.
I can tell you now that you are wasting your time because the first thing he will tell you is that you can not use it is an EI registered aircraft and consequently it is of no use to Irish pilots. Irish pilots can already fly VFR out of sight of the surface with a basic PPL and don't have the 10Km special VFR limitation because they are UK only licence restrictions. So all you want is to be able to fly IFR.......which requires an IR according to ICAO.
The fact that the FAA does not also is quite a big factor since the long long long term aim is to integrate the two systems.
The opinion of professional pilots has not changed since the introduction of the rating and is one of the reasons for Class A at lower levels in the UK.............to keep these pilot not trained for extended IMC, not able to complete a series of holds and not familiar with SIDS, STARS and unable to fly them in Class A which loads the system.
The SE IR is quite cheap for a 50 odd hour course in a well equipped aircraft.
If you want to fly IFR then you will put the work in.
