A competent smith might be able to do something like that in the Model 94. The shell "carrier" I doubt would be the problem in that long an action. It would be more about the timing on lowering the lever, shell feed.
Given the size of the Model 94, and the size of the 357 mag OR max, it would seem a sloppy fit for the two. I have heard mixed reviews on the mating of the rifle and the 357 magnum. I doubt a maximum would be much different.
