I don't think so.
My question comes back to - what is the difference between Judah and Israel?
This passage provides perfect exegesis for how God is accomplishing the restoration of Israel and Judah as foretold multiple times in the prophets. As far as I know it's not explained anywhere else in the NT but the effects of this being accomplished are (pagans being referred to as part of Israel, tribes restored in Revelation).
Who else has held this view of Rom. 11:26?
