Granada is more the exception than the rule for the Muslim Tech Group, I would not be ok with Morocco conquering Spain and getting insta Western Tech
What someone suggested about Andalusia Formation giving you Western Tech sound pretty good, that way is just for Granada but is still free Westernization.
In that case, don't make Spain give western focus, and just start Granada western. It wouldn't change how games play out in any meaningful capacity except (marginally) easing the difficulty of re-Reconquista.
However, my point that "western focus" decision being limited to Eastern/Anatolian tech is nonsense stands. If the ability to instantly shift tech group is plausible, then it follows that it is plausible to any nation that manages to actually conquer into Europe and sustain a presence there. Put the leadership of Adal in charge of historic Ottoman territory and have it conquer Wien, and it's hard to make a case that if such an absurdity happened, it would be implausible to do "western focus" while the Ottomans could have, whatever "western focus" means.
If Vijay or Korea find their way to Danzig, it's no less plausible that they'd be western than Perm doing it. From a balance perspective, disallowing weaker tech groups the decision is utter nonsense, so presumably the justification for Anatolian and higher only is historical...even though the button itself isn't historical
