WI: Theophilos of Amorion lives longer

What if byzantine emperor Theophilos had not died at the age of 28 in 842? Could iconoclasm continue?
Could his religious policies cause an earlier east-west schism? And what are the effects of the absence of the macedonian dynasty?
 
One last bump.
Had Theophilos won at Anzen, could his reign be stabilized? Could he go for Crete next?
In case iconoclasm survives, how will relations with the Arabs go? What about the Khurramites?
