I think it would be great to see those unit in game 

 Not sure if anyone would us them for a long time, but just to show that it is possible to create new skins very easy (believe me - it is). The minimum to do is just replace pieces of png files, more you can achieve by editing also csv files (what, how & why? Was described in few topics here). If you are still interested I can find those posts and answer your questions if any, because I designed units and map skins system. [;)]
 
 P.S. Maybe it will be opportunity for me to create complete tutorial about making skins. But I would need your help guys - I don't now what is hard to do/understand from your point of view.
