I think the technique of using reduced wing loading (with the thrust vector at 70 degs) used to get them beyond "coffin corner". Once the wing tried to support the full weight of the aircraft, they were in deep trouble.
OK, that's a tricky case where you might indeed achieve an even theoretically unrecoverable coffin corner.
But it depends if the plane when completely chopping power and keeping the same lowered wing load will be accelerating before you can start re-loading the wing. Depends on excess thrust on the way up and drag on the way down. (High SET and low drag would be the ticket to the ultimate -and quite surely fatal- coffin corner experience with this approach)
