I don't know how it could happen, but it would be interesting, because things would barely be changed from the Byzantine perspective (see Latin Empire) but western Europe would obviously be more favourable. Turkey (probably not the 'Ottoman' Empire, due to butterflies, but some other dynasty) might be regarded in a similar way to a more potent Hungary, i.e. used to be barbarian invaders and are still a bit weirdly alien, but are basically good chaps now. Also, I wonder if Catholic Turks would crusade against the Holy Land and become stewards of Jerusalem: it'd be a heck of a lot easier for them to hold it than the western Christian powers, after all.
