I don't know much about it, but CitOW is based on the Warhammer universe. You should be able to find a suitable miniature from there that will meet your needs, but it may cost more then you're interested in spending.
They'd also take way too much room on the board. Some of the smaller areas already get full if a few players decide to squabble there.
But then again... if you're glitzing up your game with official Warhammer miniatures you're probably capable of getting a larger, textured 3d board/table to with those.
