Sprite Autocreation

I am creating a 2d adventure game with over 20 characters, all based off the same sprite sheet, just recolored. They all have the exact same setup, (animations, control scripts, animation controller, etc.) and I was wondering if there was a way to give Unity the complete sprite sheet and automatically have it create a player object, or if there was a plugin for that. Otherwise it would take me an extremely long time to re-create the animation controller and component settings for every single player.
