So basically what's needed is something to encourage large scale migration from Iberia to England a la the Saxon settlement?
Well, it seems then that the easiest route would be to use that idea Xwarq mentioned of having the Iberian Christians flee Muslim persecution. This seems to require a more aggressive/rapid Muslim conquest of Iberia, so how to bring this about? Sorry, not too sure about specifics.
Still, even with a larger invasion, that doesn't really mean the Iberians would flee to England of all places. Likely they'd just move further north into France or maybe even Italy, given the closer distances and similar climates.
Thus, the question now seems to be; how to drive Iberians out of mainland Europe altogether? What event(s) could possibly force a sufficently large series of migrations to an island nation, when there are far easier areas to resettle?
