I'll make a map now. Unfortunately I think only the Iberian-possessions of the Aragonese Crown will seceede, but I'll look into Sardinia. Basically, this is only going to succeede if the revolutionaries (both Muslim and Protestant) are actively backed by the Ottomans, Algerians, and French like almost happened OTL (OTL the Ottomans sent like 10 ships to attack the Spanish in Valencia, but the 10 ships never showed up in the port to begin the siege). I'm worried at how the W. Roman Catholic-Aragonese might react, but I suppose if the Muslims and Protestants promise freedom of religion and the RC Church not to be messed with, then things should go okay. Hell, even the Bishop of Rome back then was nervous about the ever-growing territories of the Hapsburgs; the Papal States might send some Swiss Guards and other mercenaries to help the Catholic Aragonese. So you'll probably see two factions revolting-the W.R Catholic Aragonese supported (probably secretly) by the Papacy, and the joint Muslim-Protestant coalition backed by the French-Ottomans-and-Algerians. The two sides won't work together, but for the sake of pragmatism won't exactly oppose each other. By the time the revolution is over, the two might threaten each other, but when the Muslims-and-Protestants promise the Catholics freedom of religion and no religion of religion, they might back down. Or since the Catholics are by far the majority, they might be the ones in power. So we'll either go with the Pope putting some relative of some monarch on the throne, or with the Calvinist-French King putting a Calvinist king on the throne. Regardless, whether the Papal States like it or not, the French will have quite some sway in Aragonese affairs.

The capital would definitely be either Barcelona (where the later kings of Aragon resided) or Zaragoza (the old capital), although with the influx of Muslims and Jews (OTL Jews expelled from Iberia left for Thessaloniki in droves, ATL they're just go to the much closer and Hispanic-city of Valencia. Greek Jewry also survives, as does the Yevanic liturgy liturgy, also a plus) will cause Valencia's (where most of the Aragonese Muslims resided) population to swell with upper-middle-class Jewish and Muslims refugees, probably making it the financial capital of Aragon and if we compare Aragon to the United States, then Valencia will be the New York with Barcelona being the Washington DC and Los Angeles, and Zaragoza being the Chicago. All in all, all these refugees will do wonders for the Aragonese economy.
