In this AHC,we need to make significant regions of Mexico Basque Majority wherever suitable. Basque have been under Spain always so they would come with Spanish peoples. So since Basque are a distinct peoples in Spain,they would colonize Mexico as it is very suitable wherever suitable and eventually make it either near majority or a majority with a large minority of others. Hence the range would fall in 45%-65/70%. The rest would be Spanish Mestizo or Amerindians. So how would this Basque Mexico be in the modern history of North America?
