Without flying 2 days would be needed, yes. It’s a long way and there are some substantial bits of water to cross.
A one country pass is only valid within that country, not for travelling to/from that country.
Yes, there are trains linking major Irish destinations, the timetables aren’t currently in the Interrail systems beyond December 7.
For times look at www.irishrail.ie and www.translink.co.uk
All trains in Ireland are valid with Interrail, buses, trams and ferries are not. Ferries between Britain and Ireland give a small discount for Interrail holders but there are other options that may be be better value with non-interrail tickets.
Regular fares in Ireland bought from the operators are not that expensive and may be better value than Interrail.
The railway lines are not as extensive in Ireland as in some other countries and buses may be required to get to some places, Northern Ireland in particular has very few railways.
Be aware that In Ireland (and most of the UK) on December 25 there will be no public transport, Dec 26 will have very limited service and Dec 24 is relatively normal up until early evening with services finishing earlier than normal.
Where are you starting from?
You could just about do Malmö<>Dublin in two days, with an overnight in Brussels. But Stockholm would be harder.
Coming back to Sweden, it’s a bit easier. As long as you reach Hamburg on Day 2 you can take a sleeper to Sweden.
Either way, it’s a lot of travel if you try to do it in 2 days.
