Hi,
You can use almost any lens on a HCam Master TSII. I use it with a pair of Contax zooms. Those lenses are for 24x36, so they don't allow shift but work fine with tilts.
The Canon 16-35/4L works fine on the HCam Master TSII, too.
I considered buying an older MF zoom lens, like Pentax 645. MF lenses have larger image circle. But, in my world shifts are mostly usable with wide angles and with longer lenses I mostly use tilts.
This page illustrates some ways to shoot:

https://echophoto.smugmug.com/Technical/16-354l-and-Master-TS/The master TS allows for +/- 15 mm mechanical shift or 10 degrees of tilt, both are quite a lot on 24x36 mm. Shift is often limited to say 10-12 mm due to vignetting.
This shows some Hasselblad lenses on HCam Master TS, used for stitch Pano:

A tilt-shift zoom would be great, I often get pushed up against walls shooting architecture & interiors and would love the flexibility. Are there any engineering constraints? I see people using zoom lenses with Arca Swiss setups here and perhaps more relevantly, the HCam Master TS / HDS.
Is it a case of these photographers generally requiring extremely high IQ and so a zoom is out of the question? Honestly I think the latest crop of 16-35 zooms are probably sufficient for most applications - distortion is there of course but easily corrected.
I would love a 16-35 PCE native on any of the FF mirrorless offerings that will be available this year, I know the HCam has swappable mounts and I may end up going the Canon 16-35/4L route but honestly I'd love EXIF, aperture control and lens corrections.
