Not likely for Iberia. You would really need an early PoD to change how Al-Andalus came in existance in first place.
See, the Arabo-Berbers represented in the middle of VIII century a tiny, tiny minority in Spain (at the very best, 20 000, mostly Berbers for 3,5 millions).
The Berber Revolt and the Umayyad takeover in Al-Andalus having efficiently cut the peninsula from arab reinforcement they ,in order to preserve their political supremacy, cloisoned their rule making only the arabized population having a possibility of a power position (and it didn't really was the case up to the X century, after decennials of almost complete anarchy and revolts).
If you add that the need of constant warfare (the emir/caliphe/ruler legitimacy depending on his capacity to efficiently raid or prevent Christians to advance), a regular division (the big regional rulers acting often most idependently and not feeling themselves that much tied to a central authority) that led rulers to or suffer rebellions or to waste ressources preventing them (sometimes both) and appearing as a target for Muslims neighbours as well than Christians (that managed more regularly to unify themselves and that, at the contrary of Al-Andalus, beneficied from support from neighbours).
Each of these factors alone aren't enough to make it crush, but the whole thing is a serious issue.
At best, I could see a Berber takeover of southern Iberia, efficiently maintaining a little Muslim Iberia but it wouldn't be Al-Andalus (more like a transcontinental Morocco)
