I suspect "will be fixed in a mod" will be the answer to this one. I've been doing a little experimentation with swapping models around which I've had some success with but not 100%. Once mesh importing is done (which it almost is in Norbyte's tool set by the look of it) that may unleash a number of cosmetic mods.
The usual thing when mentioning mods applies, in that modding isn't really endorsed at this stage so this would be totally at your own risk: it's not yet officially supported in any way, including any game that uses mods.
