I'm not great with maps, but:
Egypt includes Sudan, minus Darfur and Christian/Animist areas, as well as Gaza.
Israel includes some of the large settlement blocs and the Golan Heights, but not the Wadi 'Ara, Rahat, or the "Little Arab Triangle" in the Galilee around Umm el-Fahm.
Lebanon is smaller and majority Christian (similar to Ottoman-era Lebanon).
An independent Jabal ad-Druze based in the Chouf mountains.
An independent Alawiya that includes Hatay.
An independent Kurdistan in Kurdish-majority parts of Turkey, Syria, Iraq, and Iran.
A "Khaleeji Federation" led by Oman and including the OTL UAE, Qatar, Bahrain, Hadramut and Aden. Ibadi-led but tolerant.
A parliamentary Hashemite monarchy in Saudi Arabia, north Yemen, Jordan, the land-swapped West Bank, interior Syria, Arab Iraq (Sunni as well as Shi'ite), Kuwait, and Khuzestan.
Iranian Azerbaijan to Azerbaijan.
Southeast Iran belongs to independent Baluchestan. However, Iran also extends east into Afghanistan, taking in Herat and Tajik majority areas, all of Tajikistan, plus Bukhara and Samarkand.
