What i need is to make basically a new model with the modifications the morphs do. So if the model is loaded again no morphs is in the model

Why?  Is it just a memory issue?  You can combine all the morphs you used into a single morph, if that would help. 

If FBX can include morph targets, why not just leave them in?

BTW,  you might have better luck if you ask this over at DAZ.
