How to Change existing leader Art

[Shirotora Kenshin]

what i Want to achieve Is to make Custom leader Screens and icons to Change Japanese hojo tokimune to another leader of My Choice. I Dont Want to make a completely new leader, i just Want to edit the Screens and Icons of hojo tokimune , and of course give him another Name , so that i achieve a nee leader without making a new leader and all this as a Mod...
