Is the other set of jaws otherwise exactly the same as the set currently installed? If so, then yes. But it isn't as simple a matter as just changing all three jaws to the other set. As unless there is actually an obvious difference between the two sets so that it is obvious which three and three go together, there are about 12 different combinations to try.
It seems as though there was yet a third version of legs but that could be a false memory. Your lathe also has the second version of change gear cover and also the first version of the front mounted motor switch. I think that the first motor switch was inconveniently mounted on or in the line cord dropped loose behind the lathe.
