BF2 clone sides with skirts

[Kit Fisto]

I wonder why no one has made a BF2 sides WITH skirts? Napseeker seemed to be able to do it in his Empire vs clones mod ( http://www.swbfgamers.com/index.php?topic=819.msg9625#msg9625 see pictures ). So how come no one can do it for 2 troopers of the BF2 sides? Can't you just use the stock ARC trooper model then re skin the trooper and re paint the skirt? Could someone actually make the real BF2 sides with the Heavy and Sniper trooper having skirts! Use the this pilot model though. (http://images.wikia.com/swgames/images/6/6d/CloneEngineer.jpg ).
So is that easy to do or does that take like 15 years.
