there is no such package to my awareness, possibly one around the forums.
to test textures, you can use uke, tori or any other player who has a full set of texture items.
simply direct to their customs folder (inside your toribash folder, for me that is: C:\Program Files (x86)\Steam\steamapps\common\Toribash\custom if using steam.)
then insert the textures as .tga files with the name of the bodypart, such as head.tga would replace the existing head file ingame.
to get an idea on names, i took my folder as example (owning a full texture set)
(you get the idea how it works)
to view it ingame, go into singleplayer or anywhere else and type /lp 0/1 (depending if you want to show it on tori/uke) playername.
example: /lp 0 unicorn
to make uke/tori/the player appear as usual you can either delete the folder inside the customs folder of them or type /dl name which would download automatically all the up to date textures of said person.
feel free to ask if something is unclear.
