I believe this question is trivial,
Minion A & B have eternal vigilance on them, Minion C announces an action,
can Minion A & B both burn 1 blood to untap and attempt to block, or do they
have to do it one a time? (this situation of course assumes they are
eligable blockers)
Since only one minion can attempt to block an action at a time, I believe
that answer is no they cannot attempt this course of action.
