I suppose the numerous posts over the years show that his question is not as silly as some seem to think.
I personally came across this problem trying to formulate this sentence (GRE essay ...)
"Thus, the heroes of today are no longer living individuals but dead anonymouses." (following a point about how the 9/11 firefighters are some of the last modern heroes because unlike with celebrities, there is no chance of tarnishing their reputation through media scrutiny)
In this case, I think, it would be nice not to resort to "dead anonymous persons" in order to keep the living dead, individual anonymous.
