This is tangential, but “More Safe” is a pretty silly name because of the English word “safer”. That, however, would be a terrible name.
I suggest the more memorable, more sensational, more badass sounding name, “Less Risky”.
Less Wrong + Less Risky + Less Awkward = More Awesome?
I was hoping you were going to suggest “More Safer”. That would have been awesome-er.
MoRsafe? Less Wrisky (ugh, no)? Antidangerosity?
Edit: What I like best about “Existential Risk Reduction” is that saying it usually provokes the response “ERR...” to which I say “Yes, exactly!”
