The view camera bodies with bellows will work better in this regard (the clearance) with certain lenses, but when you get down to the Canon TS-E lenses, the standards are nearly touching, so you're still running into partially the same problem. There may be a little more clearance due to how the Fuji bodies mount on the F,M,Universalis, vs the RM3di, and the 50 and 100s will definitely mount and work on the view camera, but shifting might be hampered on the side with the grip some.
On the 100r, one can hope, but if conversation on various forums are any indication, it seems unlikely. I personally think they probably would at some point, it follows their X mount strategy of different body styles for different folks and each upgrade in sensor tech usually gets all the different body styles... but that's just my guess. I wish they would just put out that concept camera from when they first announced the GFX that was totally modular and was basically a digital back with with the lens flange already built in, and attachable grip, view finder, etc...
