I'm going to try some texture on my side to see if I can help you, like extracting item images from 4u on 3ds or 3u on wiiu. sorry for my bad english I'm french ^^
EDIT : You try to use this ? http://forum.xentax.com/viewtopic.php?f=16&t=12599
EDIT 2 : Here some models but i don't know if the quality is better than bases textures https://www.models-resource.com/wii/monsterhuntertri/
EDIT 3 : I started extracting all the texture of the Wiiu mh3u monster and I'm going well
EDIT 4 : A preview of the texture of the first monsters http://puu.sh/yyg9f/b7b8743838.7z
