Muslim Habsburg Empire

Depends on what you mean by "Muslim Hapsburg Empire". If you mean a Muslim state encompassing the area of OTL's Hapsburg monarchy, an earlier and more successful Muslim push into the Balkans should do the trick. If you mean the actual House of Hapsburg converting to Islam, that's going to be much more difficult.

Yeah. Suleiman winning everything is enough for the first thing, but as for the second... well, they didn't frame themselves as the bulwark of Christendom for nothing. Both branches were on the front lines.
