Would it be possible for the Irish, just like they did in Dal Riada, to start off colonising Anglesey, Llyn and Dyfed along with other coastal areas and by the end of the Viking Age (bonus points if by the start of the Viking Age)have subdued and Gaelicised everywhere west of the seven and be in a position to prevent the Saxons from taking those lands? Thus Brythonic languages only survive in Cornwall and Brittany.
What would they and ATL Wales be called?
Would this scenario make/require Christianisation of The Gaels by Patrick to not happen and instead happen after the Saxons?
Would these people have a better chance at achieving unification by 1066 than the Irish and the OTL Welsh?
Considering that these Gaels would be less peripheral than the Scots and Irish, would their existence manage to butterfly the idea that the Gaels were a barbaric race?
