As I understand this, it would be easy to create morphs from a base geometry *.obj, but when you want to create new morphs on top of already existing morphs, you will might get into trouble, because you will have to deal with splitting up body part seams.

Not if the body parts are never split up, say through the use of a script or plugin, or export method to handle this. Where you absolutely would get in trouble is that the baked in morph state would be applied again, doubling its effect. It would be useless as, say, an adjustment morph to modify the specific state of another morph. This is called morph telescoping.

If you morph over a morph as a default state, return it to Poser, subtract it, and are left with only the new result (the difference) the new difference morph will behave as if it was created over the subtracted morph but will not double the baked in reference (telescoping) because it has been subtracted.

How might you subtract a value of 1 state added to a value of 2 state?  By subtracting 1 and producing only a result of 1 state.
