Then again, the bone assignments might have to be transferred somehow. I'm not very steady in bodymeshing, but maybe Bloom or someone else can help you if you don't know how to do it yourself...
You can transfer the bonedata with Unimesh objx ex/importer, done in a sec.
And thnx for the link, makes it even easier as i saw the suit didn't have a pregstate included.
If you ever want to have a go you:
-Import your mesh in Milkshape(without the morph('s))
-Export as objx file and save as body
-Start new and import the same mesh again, this time with the morphs
-Delete the base mesh and keep the morph
-Rename it to body
-Export as obj file
-start new and import the obj file
-import the objx file
-export
The mmorph now has the same data as the original base mesh and can be used ingame.
You could download TMO's mesh/outfit make her pregnant and stop pregnancy time but i can popout a mesh, no problem.
