Well yes, but you could also simply use it as an exceptionally sharp full-frame prime, which wouldn't be the worst thing in the world.
I may borrow a 24mm TS-E from CPS to see how much difference I can tell after digital lens optimization to my current zoom. I think that I'll be able to see it, even after DLO applied to the zoom.
