DIRE WOLF + NEW BIOME

I've been thinking, and asking around. I've always wanted to give a good idea of something, something I love and enjoy, why not Minecraft? I love wolves, they help you Fight off other mobs, protect you, they're good companions, however, These wolves are small and die easily. I have an idea to add a rare larger stronger and hungrier wolf, the dire wolf. You can find these wolves in an enchanted forest through a rare portal, this portal is blue, it takes place within the crack of a large abnormal tree which can be found anywhere. This portal leads to the enchanted forest which holds dire wolves. The aggressive mobs with the enchanted forest could be enchanted witches and more. In order to tame these wolves, you can use bone blocks, raw meat blocks, etc. These dire wolves aren't normal they should have pattern and glowing fur, eyes or mouth. A friend of mine says I should bas them off of "tibetan mastiffs" these wolves don't attack other players if the owner of the wolf was to punch a player, the wolf would not attack, these wolves attack creepers, creepers should be scared of these wolves, it would bring serotonin to Minecraft players.
