"Yeah, but then you have to dress her."

And where is the problem ?

If the clothes have bodymorphs, just use the same dial settings for the clothes that you used for the body.
And the nice thing about magnets is that they can be saved and then reused for the clothes, too.

Or spawn a full bodymorph from the new bodyshape, and use that to make the clothes fit with one of the cloth converters that are out there.
