How to change model of the Hero that u are controlling?

[1KaitouKid1]

I have play a lot of rpg that the Hero have skin. After using JJ Cheat Pack i realize Hero will be identified to save to the File Save of the RPG map only after being picked instead of the Hero of the command "-spawn unitID (skin of the hero)".
Is there any cheatpack that can help me to apply skin into the Hero or any solution for this ? Exampe: Changing the Idunit of my Hero to IDunit of the Skin.
P/s: I have taken the IDunit of the Skin because I have injected JJ cheatpack into the map. Sorry for my very bad English!
