The more I considered your points, the more I think you are right. I will still say that I do not think you can equate ethnic Israel with Spiritual Israel (Romans 9 makes that abundantly clear), and many of the promises are fulfilled in the person of Christ.
Some of these are points of non-dispute, I think. I know of no one who doesn't acknowledge that "the elect remnant" is a subset of physical Israel. But that is a far shot from saying, "Therefore, all the 'cursing' prophecies are literal and for the nation of Israel, and all the 'blessing' prophecies are spiritual and for the church," as amills must if they even allow themselves to come THAT close to the actual details (i.e. words hello, plenary VERBAL inspiration) of prophecies.
