Well, you could, but it wouldn't work the way you're wanting it to. You'd have to separate the preset into three files for head, body, and tail (or maybe not) and then rename the file(s). Then you'd need to edit the markings.cfg file so it would accept every newly converted preset file as a marking, and then you'd need the person wearing the preset to download the same markings and markings.cfg as you were using. :/
