There is something very similar on V-Admin. BAsically in that Admin Script, each user has their own file with their details such as bank, level, kills/deaths and the usual stuff etc. Their is a variable that checks the skin. If the user has Skin=999, then nothing happens, but if it is not 999, then the player has their skin set to that value as in their user file.

I won't post it here, because Yaheli might not want me to post it. But what you can do is look at the V-Admin filterscript. It's in there. PM me if you need more help.
