Good grief. I can see how in the hands of someone less wedded to strip continuity but with the strip's history to play with might just be tempted to say "You know what? Dredd clones plus Bad Bob Booth plus mutations? Yeah - let's make Death and his buddies out of clones of Dredd!"
Sure, it's expedient, but it's not somewhere I'd want it to go.
But then, I'm firmly in the 'Anderson should have a spin-off and Death should be the big bad' camp because he's HER nemesis, not Dredd's.
