I already check into trying to get the Hannibal resized without shrinking the unit... and cannot be done due to offsets not able to put the Elephant in the civ circle. As Plotinus stated, some of the unit would get cropped out to make it work.
Now the unit can work but it's size would need to shrunk down a bit; which wouldn't take long. In fact the only way to do it, without re-rendering the whole unit is to:
Resize the Storyboard itself (first changing the frame borders to ff00ff so they do not blend and bleed into surrounding pixels.) Then create FLC's from that. So fairly straightforward. If H.Balck doesn't mind, I can do that.
