Hey guys, I haven't tried this yet, But there is a easier way to get this to work. (To get the mii name)
First, after you homebrew your vWii and get Mii Installer, Go to
http://www.miisearch.com/mii-creator.html
Make your mii how you like it if you want to.
Second go to "Save" and "XML". Go to mii name (Highlighted in red)

Then go Back, and go to save. Save in the folder "miis" on the root of your SD Card. Put your SD Card in Wii U and fire up The Homebrew Channel. Go to Mii Installer. Then Install the mii and it is done. Simple as that.
