A few more thoughts on the 32 HR-W. I have considered this lens since early 2012, but each time I have come close to buying one, I have passed. No doubt optically it's one excellent lens, but here are my issues that always come back.
1. Cost, net to me 8.5 to 9K with the CF. I would want the CF and it's 1K alone. For the same price you are looking at a 40mm Rod and 60XL Schneider or very close.
2. The CF goes from 86mm to 105mm. At 105mm, you will not find very many slim filters even a CL-PL. I use both ND and CL-PL in my workflow in and around water. You can mount 1 86mm to the front of the lens, but 2 stacked will vignette.
3. Hood use, I like the Lee wide angle hood, used with the Lee wide angle rings, sadly Lee does not make a 86mm wide angle only standard ring. The 86mm standard ring on the front of the 32mm will instantly vignette a pure circle. So a hood solution is much more unique and dedicated to just that lens.
4. Weight, Guy already mentioned this. It's heavy. It's also delicate with a Copol 0 shutter as so much mass is in front of the shutter. There have been several issues where the lens came out of alignment with the shutter over time. Also, Rodenstock mentions that they don't recommend carrying the lens mounted to camera on a tripod when moving, as just in the process of setting the rig down, it's possible to damage the lens. (this is on their website).
5. The disc that Rodenstock places inside the lens (to show you the edge of the image circle) will cause a hard vignette at around 16 to 17mm of shift. This is a total waste of lens as this lens would easily make a 20mm shift on a full frame sensor. You can still shift to 20mm, but you will cropping a good bit of the top and bottom due to the disc. BTW, this true with all Rodenstock lenses that I am aware of, HR, HR-W and HR-SW. You have a great 90mm image circle on the 32, but just can't take full advantage of it on a full frame sensor.
I have been able to shoot with the 32mm in an Arca mount 2 times over the years, and totally love the results. I did an epic 8 hour drive to demo a used one, but choose not to make the purchase. I have tried to figure out a solution for filters and or a hood or both, but never have found one or come across one. Both times the lens did not have the CF and on full 15mm shift, there was a good bit on noise, the center frame was fine. Just means you need to bracket possibly on a shift as you are using a CCD back.
One other thought, as you will be on a 60MP, the 35 XL is another solution. It's just the opposite to the 32mm. I know it mounts to Cambo, not sure on how it mounts to Alpa and if the mount allows for shifting. You will be able to get around 8mm of shift with the 35XL on a 60MP full frame back. You will need the CF for all shots and that will take 2.5 stops of light away. Where as on the 32mm on center, you should easily be able to shoot with no CF.
