if you can get an irish passport. it still might be possible for you to use that to apply for a family permit using EU immigratioin rules not British Immigration rules. but you would have to be excerising your treaty rights, and i'm not sure from what you said if you are, if you get a family permit its virtually a legal right for your wife to live with you, unlike UK immigration law
under UK immigration law, a right to family life, they would probably tell you there is nothing to stop you living in the phils or any other country..
