I must say Jimmy, I am surprised at your apparent induction into the Art Katz "fan club". ;-) I always had the impression that you weren't all that impressed by him.
Two names come to mind, that I am surprised haven't been mentioned. Tozer and Reidhead. Both these guys emphasised much of the deeper life, and "perfection" teachings that Art ascribes to (particular emphasis in the first chapter of Apostolic Foundations). Albeit, they didn't give the kind of emphasis to Israel that he did, there is a definite kindred.
Regarding the prophetic aspect of Israel, perhaps considering [url=https://www.sermonindex.net/modules/mydownloads/viewcat.php?cid=539]J Jacob Prasch[/url]. Many who know Art, over here in Australia also associate with Prasch. Again, not that they would be in total agreement, but they do share views of Israel.
Another one from left field, regarding Israel, and the Time of Jacob's Trouble, is [url=https://www.sermonindex.net/modules/mydownloads/viewcat.php?cid=549]Chuck Missler[/url], who certainly associates the Tribulation with the Time of Jacob's Trouble. One notable difference is that Missler believes in a pretrib rapture, when Art doesn't, however the crux of the data is similar.
I doubt that anyone will ever truly fill the shoes of this stately man of God. In many ways, however, Art is the voice of obscurity. He serves the body of Christ, in that he testifies to the existence of men like himself. I have met a few men who are of like caliber, and yet they almost seem to shun the spotlight.
I for one will be forever indebted to this man's sincerity and integrity before God. Like many, I began listening to him to find fault, only to find that the fault was mine. Oh, that more could tolerate such extremity, and benefit from the revelation that comes from one who has truly been set apart for God alone, a living embodiment of the words, "Trust in the Lord with all your heart. Lean not on your own understanding. In all your ways acknowledge Him, and He will direct your path."
