Ther's no guarantee that a 35mm lens can be mounted to a medium format body; the lens-mount to film plane distance is less, so the lens would need to be small enough to fit through the regular lens mount. That's true for the 67 as well as the 645 - I don't see how you can use 35mm lenses on a 67 body. You can use 645/67 lenses on a K-mount body with the appropriate adapter, but that's easier; the extra mount-to-film distance allows room for the adapter, and the larger image circle doesn't introduce any problems.
