I was using (but it seems to have broken with 3.3):

/cast [dead] [target=A, dead] [target=B, dead] [target=C, dead] [target=D, dead] Revive

And then just move each toon's target along, to create a round-robin type effect.
With two toons dead, on one press each would receive a rez -- although with three rezzers, one would have two rezzers.
With three toons dead, each survivor would automatically hit a different toon.
And the [dead] conditional, allowed targeting a corpse directly for a rez.

Unfortunately, it seems to only allow mouse-target, then rez.
Does not hit the party, without a mouse target.
This is non-released toons.
Used to work, but needs a bit of tweaking now.
