I think I'd be tempted to get a pano setup that I can use for all my lenses rather than something that is so specific. A pano setup would also allow one to get an AOV wider than the shift limits of a lens.
That's what I do. The problem is that if you do a shift pano, for example to capture a tall building, you lose the ability to use shift to correct the perspective, and that's one reason for using a TS-E lens in the first place.
I do have a multirow pano setup, but I haven't yet tried it with a vertically-shifted lens (I've done single rows like that, though).
