It depends. I would not like to see another shoddy attempt at any gaa AAA tyoe games for xbox or ps3.
However I would love to see a game like "new star soccer" on mobile devices. Just with the buying a house and car and all that stuff stripped out and replaced with more Gaa related activities.
I think the control scheme for the matched would transfer really well.
The problem then is your limiting your target market to pretty much just Ireland which is very small which you said already.
If everyone who liked gaa and had a phone bought the game it would be a success but it would be about 5-10% of those if you were lucky and the game was really good.
