Option 1 is here.
Bethel=el-Bireh ( 31°54’22″N, 35°12’54″E)
Ai=et-Tell, 31°55’0″N, 35°15’41″E
Iron II B-C Ai (if Nehimiah 7:32 and/or Isaiah 10:28 refers to this Ai)=Deir Dibwan
Hellenistic Ai (?) (Nehemiah 11:31 could be referring to Hellenistic data)=Khirbet Haiyan, 31°54’18″N, 35°16’17″E
Beth Aven=Beitin, 31°55’36″N, 35°14’20″E (or Site 205???)
Mountain of Genesis 12:8=peak at (31°54’45″N, 35°14’39″E), Iron II Site 205 is a fifth of a mile to the east.
Valley to the North of Ai: Wadi el-Gayeh. At present, it would be hard to see anything in the valley, but et-Tell certainly had watchtowers.
Ambush site between Bethel and Ai not visible from Ai (Bethel does not matter, see vs. 17): undoubtedly the valley at 31°54’52″N, 35°15’17″E.
So, the scenario works, with two possible candidates for Beth-Aven, the clearer one being Beitin (can site 205 be considered a suitable candidate???) , and a clear candidate for Abraham’s mountain, however, Josh 10:2 is dismissed (et-Tell=27 acres, Gibeon=16). It works far better than Option 1.
