The universal minecraft editor was replaced by a new paid tool called universal minecraft tool. I have uploaded the old installer to my Google Drive and added it's link to the OP.
You can dump the mii channel from a real wii (or dolphin), and install it on your vWii, then use the feature to transfer miis from your wii remote.
