Funny enough, Disney had given them the name, but then they changed it because of the negative connotation. All the convention displays, program info, and licensed merch was given the death trooper name (and most still bear it). The original death troopers (zombie) no longer exactly fall into canon because of the EU legacy split in 2014, at least not in the traditional sense. It would be pretty entertaining for one of the star wars story movies to be a horror death trooper movie...won't happen, but that would be awesome.
