It is possible and not too difficult to set up a feed from one or both of your sky boxes to one or more of your rooms, and you can even change the channel!!
To get RTE1, 2, TV3 &TG4 in this other room aerials are needed but in the loft is never recommended, need to know where you are to recommend anything.
The other option you have for this room is Freesat, you can get an old sky box and have the menu your used to(with only the free to air channels of course) or get on of the many other set top box options out there(better because you have EPG and can get rid of the non working channels from the menu.
The latter option is not so bad, no RTE or TV3 of course, but all the popular soaps (bar Fair City) are available on BBC and ITV.
