As Inso has said, smaller scale minis end up being out of proportion. Way back when I got a load of GZG's 25mm star grunt minis hoping to use them as imperial guard, but they just look totally wrong next to 'human' minis. Even if their stature is smaller, the heads should remain about the same size, as with hands and of course weaponry, but thats not the case. Sorry to blow down your thought ship, but I seriously doubt it'll look right.
