im trying to do the same, in fact i did it, but theres more than sounds and models to change. after achieving that, when you use the "snipe" skill on your new unit, it looks fucking weird, the rifle is poiting up and your nova/ghost gets a red glowing sword from nowhere, so you might need to change animations too. changing animations is something i still cant do. :(
basically i did duplicate ghost, then duplicate nova actors, then link, then i went to the actors from my new unit, go to the "art tab inside the actors" then i changed models there.
