them to make customs for Rad and company ?

unfortunately no :/ i mean tachnically i believe you could replace 1 of them and give it a specific sprite, but the issue is Rad himself, since he's not a special unit, he changes appearance if you where to change a job. so he would actually need to be a special unit AFAIK
