I know nothing of the 250 but I think we can say with certainty that the 322 has a completely unique magazine design with no intent of cross compatibility to other models.
It’s also been noted on numerous reviews that the grip frame bears some resemblance to both the 320 and the 365, but is also it’s own unique design and will fit holsters for neither of those. Nor is there any chance of swapping FCU or barrel. The 322 was designed from the ground up to be what it is.
