It will work to approximate focus, but it will not likely be accurate. It varies from lens to lens, so you could be lucky. I'm not sure how the MPP works, but since it is a Linhof copy, it probably has a cam of some sort. On Linhofs these are matched to the serial number of a particular lens. It may be possible to adjust your cam, or make a new cam matched to the lens you want to use.
A few loose screws short of a functioning camera.
