Well, first you'll need to make a Pose file with all of your morphs for the new character.  I recommend you do one for just the head, and one for just th body, and one for both together. 

Once that's finished you'll need to make some MAT file poses for your texture files.  There are a lot of different tutorials out there to tell you how to do both, so I won't go tremendously into detail, but that's basically what needs to be done.
