Well apparently nobody likes Naruto imports unless they're freaking Sasgay or Stupid Narutard =-= or Orochimaru...
Seriously people...there's enough hacks of those three on the vault to have their own section! Granted it's not as bad as shadow the derphog...but really...*rolls eyes*
Just keep in mind that if you want to be famous for your imports, it would be better if you imported someone that a lot of people know about. For example, I don't know who you listed in your post is (except Naruto), so I would be in no way interested in those characters. But someone else who knows them would maybe be interested in them.
Another thing that makes imports interesting is the quality: A character need to have minimal issues, such as a good rig, perfect metal (or almost) and the like. Master those things, and you might get a bit more recognition.
