What if Gaelic Ireland managed to avoid English conquest? Could they even keep the High King position in some form into the present? Perhaps becoming a federation at some point? How would Europe develop? would Ireland get in on the colonial game?
I suppose you mean culturally Gaelic rather than just merely linguistically. The idea of a High King happened only a few times in any substantive manner of holding power in Irish history and was never really sustainable. Brehon Law, after all, while internally effective to a degree, somewhat stifled any processes of urbanization or specialization economically and any idea of political centralization, as Tanistry and Gavelkind were used in inheritance policies and the Kings could never seize the kind of power that absolutists did in other areas of Europe due to the constraints on them.
Ireland geographically placed would have been well able to engage in colonial activities in modern day Atlantic Canada had they developed the naval technology for it, but that presumes political unity, which would not exist.
As for the Gaelic language, that would be around still had it not been for the diaspora which encouraged the learning of English over Irish and the gradual discouragement of using it in public life. The language as it exists today only does so in a few scattered parts of Western Ireland, as well as inside the education system, when it is forgotten as soon as students leave.
I started a Timeline about this years ago, with a POD of a longer surviving Brian Born and the establishment of hereditary monarchy.
It’s possibly more likely imho although obviously I’m no expert but if one of the powerful gselicized Norman/welsh lords was wanked sufficiently. This military genius (imo he would have to be pith politically and militarily incredibly astute) warlord now high king would begin his own dynasty which would supplant and erase earlier dynasties bringing with him a centralised pholiosophy, capital and a concept of Irish nationhood. Indeed no small beer - almost Asb but surely possible.
The Ó Brians never really tried to change the system up though. They were strong within it but only to the max allowed by the system anyway. In fact, Brian's death goes to show that despite all the power he was able to accumulate it still only lasted his lifetime - the death of his son and grandson in battle most likely didn't help much either. Even if he or/and they didn't die the second he did the lords/kings forget his 'power' and start to re-assert possible independence forcing Brian's successor to go around again and subdue all. Again. If that happens each succession you're not getting a strong, centralised kingdom.What would make them substantively different than the Ó Briains?

Ooh. Could I have a link? Is it finished? Or did it just die? I had that happen with an attempt at a Habsburg wank once.

Combined with the fact that while remembered as the greatest king he actually didn't rule the whole island completely or at least through royal channels but only really held power in the southern and eastern parts of the island. To get the kind of result @Grammar Kaiser is looking for you'll either need a native king to import or form the idea of a ruling monarch rather than a reigning one or have as @Nomis Nosnibor suggested a foreign ruler come and instil these ideals. This gets you the - relatively - centralised kingdom with which one can resist invasion, colonise and influence. Perhaps.
Now time for the blatant self-advertising on this topic of myself. Look at my sig. Done. That felt disgusting *shivers*.
