I don't see the fact that the voice hasn't produced any stars, as a bad thing.....?

Look at X Factor, you won't get the big stars like 1D, Little Mix, James Arthur, Alexandra etc. returning for an all stars series. However with the voice, since they have never done much post-show, I can see almost any act happily returning, which for fans of the voice would be great.

Christina Marie, Stevie McRorie, Leah McFall, Vince Kidd, Donel, Ruti, Jermaine, Andrea, Deana etc. Can't imagine any reason for them to say no. It would be amazing imo and they could maybe do it like Aus did with normal blind auditions
