Well I figured out how to fix the prob sort of.

1)  Load in m4, and then pose.
2)  Export each body part out as a separate obj file.
3)  Load in k4. Then pose like m4.
4)  Select a k4 body part, and then load in as a morph target the same m4 body part obj.
5)  Repete step 4 until all body parts have been done.

Only prob with this to morph k4 into m4, or anything in between you have to goto each body part, and turn the morph dial. Then there is the thing with exporting each body part.
