If it's mainly poke-through and making the body parts of the original figure invisible does not work, I would try to fix it in an external editor ( I use Silo for this, but Wings should be fine too). But to do this when the figures are posed you would need Morph Loader Pro, which is a part of the Advanced Setup Tools. 

A ship in port is safe; but that is not what ships are built for.
